On this list, we tend to cover anything that is related to computers. That is true. There are lots who post a lot here. I just recall seeing some stats somewhere and me and you were the top two.

The docs seemed to have slumped some but I think it was down to one or two people for a while. I think someone jumped in the fire a few weeks ago tho. Maybe they will catch up. I'm sure it is hard to keep up with all the changes that are going on tho. Gentoo has a LOT of stuff to document. Documenting Gentoo is difficult. I think this list is a good start for documentation though. If we are so skilled, why is the Fedora dev not listening you reckon? Is the Fedora dev aware of non-Fedora installations? -- Joost

But there are no /dev/sd* entries yet for the device /usr is on. That's what udev is for in the first place, creating them. We could add those devices manually, like the essential /dev/console and /dev/null that also have to be there before udev kicks in. Might be simpler than creating the initramfs thing. But probably only with real disk partitions. For LVM, many more devices will be necessary, and I don't creating them all by hand might not be so easy. When udev does so many things these days, couldn't udev itself mount the /usr partition, and then continue with the rules in /etc/udev/rules.d/? But I really think that either udev should just not depend on stuff in /usr, or consist of two stages, one for the essential device nodes, and one that is run later, after /usr is mounted, dealing with stuff in /etc/udev/rules.d. Which will not solve the problems with a bluetooth keyboard, though. But for most of us it might work. Just thinking, Wonko

This would depend on wether or not udev (or whatever program handles the events) can pick specific events out of the queue. I think the events are placed on a queue waiting for some process to handle them and that process then does the following in an endless loop: 1) get event from queue 2) handle event In order to split the 2 options, there needs to be something that sorts them between init-level and run-level events where init-level is what is needed/possible during boot. As I currently understand it, the kernel does not support cherry-picking / multiple queues for hotplug-events and all devices cause a hotplug-event for the /dev-tree creation part of udev. A second queue will need to be handled somehow. I also don't see why udev needs to get the additional code to handle delaying running external tools when this could be split off into seperate process. This way, if the program/script that is configured in the udev-rules causes a system-crash, avoiding the handler for these to start up, will actually provide a better fail-safe.

I've had a look at the stuff at those links, and some of what they

Looking at initramfs as a modern Linux replacement for the
bootable / partition of traditional Unix systems does make some
sense, even though I think it could be made simpler.
Fot those opposed to initramfs, would you also object to /boot being
1) a manditory seperate partition
2) required to be ext2 (or one of a *very* short list)
3) having /boot/{bin,sbin,lib} containing local copies of the
absolute minimum boot requirements (i.e. initramfs in a real fs)
For my part, I don't object to any of those. The Unix boot system is
generic enough that one should be able to build whatever one wants.
Only a very few things are required:
the kernel must be accessible to the bootloader
the root partition must be accessible to the kernel
init must be available early
everything else is optional
How the distro (or user) makes this happen should be up to them, not up
to udev. I understand that udev opens up all manner of
future possibilities and these could be very useful. But I do object
to a single package breaking all the foundation assumptions, especially
when the package is now being used in ways not originally envisaged.
udev is a dynamic device node controller. It is not a hotplug framework
and should not be dictating how the rest of the stack must be arranged.

How many people complained early From what I read, he's listening, he just isn't being swayed by the argument. From his perspective, udev doesn't support a split /,/usr because of the arbitrarily complex udev rules. This is causing users to fill their bug queue with errors when needed binaries are unavailable at boot, and thus their hardware doesn't work. Apparently he has concluded that the number of people who require a separate /usr partition but cannot use an initramfs is smaller than the number of people who need udev to have access to all of /usr. Unfortunately it appears that he's taking a pretty extreme approach to solving the problem that will actually *break* the systems of that second group, which I don't quite understand the reasoning behind. As I understand it, nothing of udev itself is in /usr, but instead packages and scripts which plug themselves into udev to be triggered by various events. Perhaps the real solution is to circumvent udev and get those other packages and scripts to not put hotplug-active files under /usr. That's my understanding too, and I agree with your conclusions. The distros can easily (give enough man-power) deal with this too - they simply have to modify their rpms/debs/pkgs/ebuilds to install specific identified things to / instead of /usr. They *already* do this for packages that natively install to peculiar locations. It would make perfect sense to me for the udev maintainer to simply declare a split /,/usr not supported and let us deal with the issues. The problem, if I'm reading correctly, is that he's taken things one step further and decided to move udev *itself* back into /usr. Even still, I would think that a Gentoo patchset to revert the paths back to /lib would be a feasible workaround to this mess. --Mike

When devs stop listening to users, that causes a AFAIU he doesn't listen to people not running RHEL/Fedora (or any of the big binary distros). For a binary distro, that most likely already are using an initrd thingie, this works fine. In my mind it also makes it more difficult to support your own kernel (patches etc.) under these binary distros making you more dependent on the distro supplier. If you want control of what goes into your machine then this works less well... Now if you were a _big_ customer of RHEL that wanted to keep udev working like it currently does I think you might have some more leverage (i.e. if the developer refuses to keep things working, then someone at Red Hat would probably step in at the benefit of their customer and do the right thing(tm)).

Interesting. What are the advantages?
Mainly that it's simpler, as a bootloader should be. However it does
have some nice features, such as making nice looking, interactive
menus. You can also edit the config file by hand, if you need to, and
it's all contained on the boot partition.
The biggest problem with grub 2 is it adds a dependency on having your
main root partition already mounted in order to configure it. That may
not be available. Also, when you learn extlinux then you know syslinux,
isolinux, and pxelinux already which helps when configuring boot
loaders for those other media.
Thanks for the explanation. I like to learn, knowing how to use them
might come handy some time.
I already installed syslinux recently, I think that was necessary for the
installation of systemrescuecd on USB. Which failed, after using the
installer, the stick was still empty. No idea what went wrong, I did not
dig further into this, I was too busy then.
What I like most about Grub is the interactive shell. And that I don't
have to run a command like I had to do with Lilo after installing a
new kernel.
If you need a shell, boot a minimal kernel and shell from a ramdisk. No
good reason to bloat a bootloader with that.
I still like how I could make Grub boot a system even when I did not know
on which partition it was. This happened a couple of times, like when I
had multiple hard drives that changed their order. Tab completion or the
find command were good to have then.
And about the bloat... 450 K being used for Grub in /boot is okay for me.
Which could probably be reduced further down to ~115K when removing
stage2{.old,_eltorito} and support for other file systems than ext2.

I had this on one machine. I used the stuff that Dirk Heinrich offered

some errors. Anyway, I always wondered why this is not the standard way.
Sure, having a single intr{d,amfs} file is convenient, but every time I
want to have a look into it, I have to google the cpio syntax in order to
extract stuff. While, with an initfs, you simply see everything as plain
files in the /boot partition.

On the other hand, most of the problem seems to stem from software packages
hooking into the early boot via udev rules, and not beiong careful where they
put the executables and libraries that they reference.
Is udev (as it currently stands) really the best place for them to hook into?
Could udev be split into 2 passes, early-boot udev that only does system stuff
(like mount filesystems out of /etc/fstab, setup keyboards video), and late-
boot udev where other applications can put in any hooks they like, since the
full system would then be available.
The late-boot udev may need to do a full rescan of everything that early-boot
udev found, but didn't have the rules for yet, but I'm sure that the 2 passes
could talk to each other and sort that out fairly simply.
Or possibly just add a whole new service to use just for hooking software
packages into system events. Although this would probably end upneeding to be
a udev clone anyway.
I always have /boot on a separate partition and it is always ext2. So,
that is done. I also have a 200Mb /boot partition. It sometimes gets

could always make /boot larger too.

After all, they are fairly close maybe even a step up. Especially now. Doesn't Gentoo have a BSD target? The problem here is with udev, which doesn't apply to BSD, AFAIK. Gentoo/BSD might be a good direction to go. Also, where does FreeBSD's kernel stand, with respect to device drivers? There is a BSD target on Gentoo, but I don't know too much about it (I just use regular parts on my installs). It seems to suffer from lack of manpower, starting up and dying down occasionally. Which is a shame as it has huge potential but Linux grabs most of the limelight. Driver support is excellent. At least on server grade hardware everything I've ever bought just works, but I can't comment on desktop hardware. I've flirted with Slackware before I came over to Gentoo and the reason I chose Gentoo is because it gave me more freedom to built and configure an OS exactly as I wanted it. I was at the time thinking of trying BSD with portage, but when I was keeping an eye on it there was this start/stop development as Alan mentions and loads of packages were unstable for yonks or missing completely. This made me decide to stay on Linux. I don't think we should give up completely yet. Perhaps we need to lobby a bit more effectively (Can we email directly the dev(s)? Where do they live? Ha, ha!)

That's what you thought :) Normally, all you have to do is to boot in single user mode, this gives you a root shell without asking for a password. Unless you have changed console none unknown off secure in /etc/ttys to: console none unknown off insecure It will then prompt for a password, but even this will not help much. As long as you have physical access to a machine, you can simply boot it from a CD or via USB, mount the partitions and remove the password in /etc/passwd, or simply chroot and do whatever you want. To make it really secure, you have to encrypt the whole system. Which is fairly easy BTW. lol That is why I chose Linux in general. I want something that is secure enough that I don't have to worry about some script kiddie messing with me. Just make sure to block or disable flash content when surfing the web. BSD is one option I will be looking into if I move from Gentoo. After all, they are fairly close maybe even a step up. Especially now. BSD is elegant, simpler, and has some nice features like a file system that can be checked in the background while being in use already. With the drawback of being quite slow compared to others. But I would miss many things. I think portage is much superior these days. Builds that continue when a package fails, or even parallel builds are not possible AFAIK. The driver situation is worse I believe, when it comes to graphics hardware. And I just read [*] that some KDE guys are rethinking whether they will support other operating systems than Linux for the plasma desktop, because it may not be worth the effort.

The point is, its one more thing to break and as Alan explains, it breaks the tradition of what is required for booting up. I run into enough problems already. I don't want to add yet one more, to booting at that. I'm sure I'm not the only one that doesn't like init* stuff. That is part two of not liking this idea. I don't get this one.

I'd just wait until it starts getting to 80-90%, and think about it again. Wonko No, I'm thinking about this because one of the reasons I left binary based distros was crap like this. I didn't like init* stuff because they caused me grief when booting. I wasn't as skilled as I am now so I didn't know how to fix them. Heck, I still don't and really don't want to be forced to learn either. It's the same reason I don't use LVM. It just adds one more layer to cause problems. I *may* use LVM for data or something but not for anything required for booting. I'm sort of like this. I want to be able to boot to single user at a minimum as simple as possible. If I can do that, I can fix whatever is broke. If I install a init* thingy and I can't boot because it got screwed up somehow, I'm not going to be happy. I don't get mad often but this could be much worse than hal. Given my medical situation, I need to avoid that at all costs. One of those costs may be me picking something else for my OS. I like Gentoo but the reasons I started using Gentoo are slipping away. I'm running out of reasons to have this installed. It's like having a car. If you have a old car that breaks a lot, at some point you have to decide whether the reason you have the car is the same as when you bought the car. If you can't depend on it to get you where you are going, it's time for a new car. Cars are to get a person from point A to point B for most people. I want a OS that is simple enough to get it running but I also like the control Gentoo offers or used to. Yea, I know, Gentoo isn't that simple but it is simple in how it works once set up. Load grub, load kernel, start the init process. Simple. The init* process is

Come to think of it, given HAL's demise can you also please have a go at udev? You never know ... ;) Well, this is me. I like things simple. I have built my own computers. I have rebuilt car engines, small mower engines, worked on about every machine, except heavy equipment such as a crane, and done well. What I don't do is add unneeded junk to something. This init* stuff is one of them. If a person wants to use it, then fine, by all means use it. Thing is, this is going to affect a lot of people in a negative way. When I first installed Mandrake and didn't know a lot about Linux, I had /usr on a separate partition. As ignorant as I was, I knew it was a good thing to do. I clearly wasn't thinking when I put /usr on / when I did this install. Maybe the excitement of my new rig got the better of me. lol I have to admit, hal got on my bad nerve. Thing is, I could at least boot up to fix it. Console was still working. If this init* thing breaks, I can't even do that. Trust me, I'm going to be super duper pissed if this init thing fails. I won't care why. The point is, I don't want the thing to begin with and it shouldn't even be needed. There are better ways to do this. From my understanding, the dev is not listening. That is another thing that bothers me. When devs stop listening to users, that causes a problem. Remember hal? How many people complained early on about the config files? Lots. I also don't like that a very few people or just one person can make a decision like this that will have a negative affect on a LOT and I mean a LOT of users. That is something that needs to be dealt with. What I would like to see is this, a good stable alternative that works well with a proper fix and for that to push udev out and render it null. I think that would serve the dev right. Listen to the people that use it or people will use something else. The mdev package comes to mind here. Maybe this will push it to take udevs place. It seems there is enough people that opposes this. If a few commercial and paying people can help, it may just be the next better thing. Dale :-) :-)

I think that would serve the dev right. Listen to the people that use it or people will use something else. The mdev package comes to mind here. Maybe this will push it to take udevs place. It seems there is enough people that opposes this. If a few commercial and paying people can help, it may just be the next better thing. As I understand it, nothing of udev itself is in /usr, but instead packages and scripts which plug themselves into udev to be triggered by various events. Perhaps the real solution is to circumvent udev and get those other packages and scripts to not put hotplug-active files under /usr. That's my understanding too, and I agree with your conclusions. The distros can easily (give enough man-power) deal with this too - they simply have to modify their rpms/debs/pkgs/ebuilds to install specific identified things to / instead of /usr. They *already* do this for packages that natively install to peculiar locations. -- Alan McKinnnon alan.mckin...@gmail.com

Interesting. What are the advantages?
What I like most about Grub is the interactive shell. And that I don't
have to run a command like I had to do with Lilo after installing a new
kernel.
I guess Grub 1 will be around for a long time, and there will be no
need for me to switch soon. But I had to deal with Grub 2 on other
installations, and I had many problems. And I was disappointed because
configuring it is so much more complicated. It may have cooler features
and suport more file systems, but setting up grub 1 most of the times was
grub, root (hd0,0), setup (hd0), quit and setting up 2-3 lines in
grub.conf.

However it does have some nice features, such as making nice looking, interactive menus. You can also edit the config file by hand, if you need to, and it's all contained on the boot partition. The biggest problem with grub 2 is it adds a dependency on having your main root partition already mounted in order to configure it. That may not be available. Also, when you learn extlinux then you know syslinux, isolinux, and pxelinux already which helps when configuring boot loaders for those other media.

http://comments.gmane.org/gmane.linux.hotplug.devel/16994
I've had a look at the stuff at those links, and some of what they link to in
turn, and had a bit of a think about it.
Looking at initramfs as a modern Linux replacement for the bootable /
partition of traditional Unix systems does make some sense, even though I
think it could be made simpler.
Fot those opposed to initramfs, would you also object to /boot being
1) a manditory seperate partition
2) required to be ext2 (or one of a *very* short list)
3) having /boot/{bin,sbin,lib} containing local copies of the absolute
minimum boot requirements (i.e. initramfs in a real fs)
On the other hand, most of the problem seems to stem from software packages
hooking into the early boot via udev rules, and not beiong careful where they
put the executables and libraries that they reference.
Is udev (as it currently stands) really the best place for them to hook into?
Could udev be split into 2 passes, early-boot udev that only does system stuff
(like mount filesystems out of /etc/fstab, setup keyboards video), and late-
boot udev where other applications can put in any hooks they like, since the
full system would then be available.
The late-boot udev may need to do a full rescan of everything that early-boot
udev found, but didn't have the rules for yet, but I'm sure that the 2 passes
could talk to each other and sort that out fairly simply.
Or possibly just add a whole new service to use just for hooking software
packages into system events. Although this would probably end upneeding to be
a udev clone anyway.

Given that I do not understand the ins and outs of udev, or the way gentoo and upstream manage such proposals and ultimately accept changes, why don't gentoo devs raise alternative options with the Fedora dev or who ever had this idea upstream that udev code effort is more precious than all the workarounds (initramfs, repartitioning, etc.) that some of us have to go through? The alternatives I've read so far that advocate the avoidance of the imposition of an initramfs or merging /usr into / for the sake of a udev design choice, seem more 'intelligent' to me - in a gentoo principle sort of way. On the other hand, for a binary distro the udev dev approach would of course seem less disruptive and therefore our small gentoo user base may need to shout really loud to be heard. Do we get to vote on this? Not really: you can vote with your feet and use another distro/operating system. But the choice is theirs. Can we make a difference other than venting here and in the forums? Yes: design and write a different system. That's a really poor answer. You are offering two distasteful options at either end of the spectrum when the real solution is plainly obvious right in the middle: Communicate to whichever devs are making the calls, explain the issue caused by the proposed changes, open and entertain dialogue, let all voices be heard and let sanity prevail. You have consistently offered only two realistic options: their way or the highway. This presumes that the devs involved are impervious to the concept of dialogue at all, and cannot be contacted or swayed. You see, none of that is true. There is *always* a third way and it is almost always the best possible route to follow. In the case of Gentoo, the dialog is having place in the dev list, at this very moment. In the case of Fedora (and, I think, OpenSuse), the dialog is actually over. The Gentoo devs are just going with the flow. (This is how I see things, I could have some facts wrong). Aha! This is I think where it went wrong. The Gentoo devs should *not* have gone with the flow. Giving the udev code primacy over the conventional FHS way, rather than spending some more time to sort out the genuine cause of the problem (udev) is something that in this case affects the Gentoo principle of doing it the 'Gentoo way' - more than binary distros who are already using initramfs. So this is a Gentoo user/use case argument more than upstream devs may care to examine. It is not an arbitrary decision, and it is not from one developer (this kind of things never are). The dialog happend (or is happening) among those who construct the stack or the distributions. We have a say, of course (we always do), but I don't really think that it should be that important. I really, truly believe that the decision is (and should be) in the hands of the people actually writing the code. You have made this point clear enough, but the way this has been decided clearly cuts across the choice of freedom that Gentoo users had until now. People are getting upset and using an initramfs, repartitioning, or becoming Linux developers overnight to write their own udev code is not a particularly attractive option for most Gentoo users. I think this is how Linux rose to be what it is today, and how it will keep going on strong. Sometimes mistakes will be made, and some users will be burned by them. I (personally, IMHO, etc., etc.) don't think this is one of those times. And that is way I'm expressing myself in this thread. Fair enough. It is evident that there are quite a few of us that disagree with your view on this matter. I think that in this case some devs followed what is convenient or expedient, rather than choosing a more purist/elegant approach that fixes what's broken (udev) without affecting adversely the wider ecosystem. That is all. I know what I say a lot of people don't like, but I think it should be said, clear and loud. I believe that you have repeated your position enough times that we all get it. Your position though advocates a design solution which cuts across the Gentoo way of doing things. This makes Gentoo less valuable to some of us. -- Regards, Mick signature.asc Description: This is a digitally signed message part.

I been using Linux for a while. Let me see if I understand this
correctly. As I understand it, when a system boots it needs /bin,
/sbin, /lib*, and /etc and nothing else other than /boot for grub to
load the kernel. Those directories are for booting the system and for
system operations. That is my understanding of how it has been since
further back than I care to explore. Things that are used after a
system boots, such as things in the default runlevel or KDE, goes into
/usr somewhere. This is the reason that /usr and /var can be on
separate partitions. I have always understood that /usr and /var can be
put on separate partitions for security reasons or to put some larger
partitions on separate drives. If I recall correctly, websites files
are under /var. Those can get pretty large quick I would guess.
So, now someone has decided to change this and it seems a few think this
is nothing users should worry about. I don't run a large server or
anything but this still worries me. I don't like the fact that the
changes I had planned will now require me to also install one more thing
to break. My system is simple and I like to keep it that way. The
fanciest thing I have is a camera and a printer that I use once in a
blue moon. I want to put /usr on a spare partition because it is
growing fairly quickly with the KDE4 updates and others too. Now, it
looks like I have to do a whole redo of everything. Something that was
simple just got complicated.
My choices are:
1: move from Gentoo to something else. I'm seriously considering this

2: Stick with Gentoo and hope this is corrected like hal was dealt with.
2b: Go with LVM for everything and have a init* to boot.
2c: Move /usr and use init* with no LVM.

Again, it is a joke but my point is, very few people are liking this. That alone should say a lot. I know, but Open Source has never been a democracy. It is a meritocracy. No matter how many get upset by a change, the opinions that matter are from those writing the code. I don't agree. There are people with opinions that matter even though they don't write the code. There are plenty of Open Source projects where the opinions and comments from users also matter. And if those users actually put time and effort into the documentation/support side they get listened to more often. This is a very few people forcing a change that no one wants. That's a contradiction, isn't it? The few people forcing the change want it, I hope. Ok, lets do it by numbers. People forcing it: 5 (maybe? not that many more) People liking it (including the above 5): 10 (maybe?) total number of users: 1,000,000 (pulled out of my head) Percentage of users liking it of all the users: 10 / 1,000,000 = 0.0001 %. That's a very low number that in most cases would be rounded to 0. Eg. noone. You seem to fail to understand that. I don't agree with the few people and the no one wants parts. I understand that this change is upseting some people, but I don't think you (nor I) can say for sure if it's even a majority of Gentoo users, I think the majority of Gentoo users will happily continue the way they have been working with their systems. Then, when this change gets forced upon them, they will all start complaining loudly because all their systems no longer boot. and even if it were, again, Open Source is not a democracy. Actually, it is. People tend to vote with their feet (ok, downloads) and if they don't like something, they walk away. Personally, if I'm going to have to start running my Gentoo box like a binary based distro, I may as well use a binary based distro. If others feel like I do, then Gentoo may start losing users. I got away from Mandrake for reasons such as this. That's your prerrogative. And that's why I'm saying my word in the list: I'm pretty sure many users in the list (which are not all the Gentoo users) are not really upset with this change. The other POV has to be heard. I haven't gone through the whole thread, but it seems to me there are several people against this change and only one who is for. I kept quiet as my arguments were already being raised and I dislike +1 postings. But in this case, I feel an exception is needed. I'm going back to my garden. You have fun promoting this mess that is being created. You seem to enjoy it a lot. I'm not promoting anything. Just want to get into the record that some users don't mind this change, and some of us even welcome it. Why would anyone welcome a change where an initramfs (or whatever it's called these days) is necessary just to boot your system? This also needs to keep getting updated whenever a needed piece of software is updated. I tend to update the software more often then the kernel. Now, I'll have to rebuild my kernel more regularly. Even though, from my point of view, nothing will have changed. -- Joost

Correct.
/ is often set up with only the minimal packages needed to guarantee
that single user mode will work correctly if the only thing mounted
is / itself.
Things that are used
after a system boots, such as things in the default runlevel or KDE,
goes into /usr somewhere. This is the reason that /usr and /var can

and /var can be put on separate partitions for security reasons or to

Correct again.
/var is for variable data, usually persistent data like log files,
databases, web sites, caches. It is writeable by root and system data
goes there (as opposed to user data).
So, now someone has decided to change this and it seems a few think

The truth is that with these changes your system will continue to work
just fine. Just like my laptops work just fine (I have one big
partition with another for /home on laptops).
My laptops don't need a separate /usr, but my servers do.
So it really looks like someone is forcing a change that makes udev's
life easier and potentially wreaks everything else in doing so.
My choices are:
1: move from Gentoo to something else. I'm seriously considering
this one. If I can learn Gentoo, I can learn any distro! LFS may be

It's not a Gentoo change, it's a udev change. So you'll be stuck with
this new stuff regardless of which distro you go with.
2: Stick with Gentoo and hope this is corrected like hal was dealt

2c: Move /usr and use init* with no LVM.

That is quite a small list subset of the full list of all possible devices: All HID devices All console devices All code to access and read file systems Everything that can be used in place of a physical keyboard (serial, console over ethernet) That looks like it might be a large amount of disk space, but in fact it isn't. This very mail is being typed on a binary distro (Ubuntu): The bluez package is 1.6M. /lib alone is 331M, I use a fraction of it but it is still there. /lib/modules contains two kernel versions of 136M each. Again, it is not bounded. Today is bluez, tomorrow we don't know. That's the point of udev, really. You're still not getting it. Just because it appears convenient to make udev unbounded does not mean that all possible code on the machine has to be accessible to udev. Or that udev will potentially run any arbitrary code you might have. Or put another way, udev might be able to run anything, like say lauching KDE, but the simple truth is that it won't in any reasonable scenario. Therefore you do not need to support or entertain that possibility. The truth is that a very small portion of the total code on the machine needs to be accessible to udev and all of it (including all foreseeable code) fits into a traditional / quite nicely. There is no upper limit on the size of /, you simply make it as large as you need and put everything supported in there. Once again, and this is very important, the only things that are absolutely required to be in / is all the code that must run before /usr is mounted. That list of things is very small, and if the user or the distro happens to cock it up, then the user or distro must fix it. Why is this apparently so hard to understand? The solution seems blindingly obvious: Any code launched by udev must be available on the same partition as /. However the system is rigged, that one condition must be satisfied. And consider who is setting this up: - root, who presumably knows what they are doing - distro devs, who also know what they are doing Or are the udev devs seriously contemplating allowing udev hooks so that any arbitrary user can launch any arbitrary code that might arbitrarily be anywhere? I still maintain this fix is for a problem that does not exist. -- Alan McKinnnon alan.mckin...@gmail.com

It will only affect one out of three boxen of mine and I could surely fix that, but I am against restricting unquestioningly what I can do with gentoo, just because a udev coder didn't think it through enough to come up with a smarter solution; and then the Gentoo devs did not put up a fight in representing their user base.

Again, it is a joke but my point is, very few people are liking this. That alone should say a lot. I know, but Open Source has never been a democracy. It is a meritocracy. No matter how many get upset by a change, the opinions that matter are from those writing the code. This is a very few people forcing a change that no one wants. That's a contradiction, isn't it? The few people forcing the change want it, I hope. It's not. So far, one dev made the decision to do this and a few have agreed. There are lots of people, as noted in this thread, that disagree. Some of those people have been using Linux for a very long time. I don't know how long you have been using Linux but I'm pushing ten years myself. I suspect that Neil and Alan, and maybe others, have been using Linux a LOT longer than that. Maybe more than both of us put together. When I see a post by Alan or Neil, I read it carefully. There are Linux idiots in this world but they are not one of them. On some subjects, I fall into the ignorance category. I don't claim to know it all but some things I do know well. The contradiction part was a joke. A bad one, it seems. I started using Linux in 1996, when I started college (Computer Science, if you must know). I used RedHat, then Mandrake, then Gentoo, around 2003. After college I worked in several companies, doing mostly programming, but also a lot of system administration. I have worked with Solaris, HP-UX, SCO, and a tiny little bit of AIX, but the bulk of my curriculum is in Linux. In 2005 I got bored of being like Dilbert, and went back to school to get my masters in 2008 (Computer Science, again), and after getting back to work less than six months, I returned to Academia to get my PhD (Computer Science, what the hell), which I hope to get next year. That is not going to happen if instead of finishing writing my papers, I keep posting to threads in gentoo-user. I have some experience with Linux and Unix. I have followed the development of Linux, GNOME and everything in beetween in the stack like some people follow soap operas or football games. I think I kinda know what I'm talking about. But of course, I could be wrong in this issue. I just don't think so. I said my points and listened to very different and interesting ones. From my POV (and I say this with all the respect possible), I see a lot of people afraid of change or too worried about their pet configurations, but not a really Earth-shattering technical strong point that makes me believe this change is unnecessary, irrational, or lazy. It is incovenient? Sure, but in the long run I think it would make Linux better. This I haven't said, I think: I care about Linux, and basically Linux only. I want it to be on all my electronics, from my cell phone to my refrigerator and of course in my desktop. That is already happening, and the direction it is heading. But to do that, Linux cannot be a classical Unix. It needs to be so much more. It needs to do thinks *DIFFERENTLY*. So, even if Linux will be always able to do anything any other Unix could do, it will do it in a fundamentally different way. So if you care for a Unix boxen that only does Unix-boxen things, in the classical, 1970-way, then probably Linux is not the best option for you. And for sure *I* don't want progress stopped only so Linux is able to do the things already does in the same way, with the only argument being my script/setup/partition works now, why should I changed it? Change happens. I appreciate the discussion, and I think it was enlightening and entertaining, but I will not participate anymore. I need to get my PhD one of this days.

In my case, I only need the initramfs in order to scan for logical volumes and to open the luks-encrypted root partition. Other partitions are mounted _after_ the initramfs was left. With the UDEV change, /usr needs to be mounted from _inside_ the initramfs. So you're right, much more stuff is being needed. The above libraries and the e2fsck binary total to 2.3 M here. The initramfs is gzipped, so we have 1 M. Still not _that_ much, but I don't know what else might be needed. And something must put it into the initramfs... I assume genkernel will get this feature? Surely the Gentoo devs won't expect us users to do this all by ourselves? What kind of libraries do you have inside your initramfs? I have no idea... but I can have a look. Ah - none at all. /lib contains a directory with all sorts of keymaps, an empty luks directory, and some 56 kernel modules. Wonko

You hit it, for some reason I put /usr on the root partition without thinking. This is where I am now: rootfs19534436 10693048 8841388 55% / Over half full. When I have a critical partition get over 60%, I start looking for expansion. Moving /usr was my plan but someone stole that from me I guess. Now I got to figure out what I want to do next. Yes, I also feel sorry for guys like Alan. But for us desktop users I think's it's not such a big deal. I'm a desktop and a (personal server) user and I think it's quite a big deal. I want simplicity; adding layers increases complexity. I think it's the same for Dale and most other people objecting to this. To me it's a very big deal (this is a deal breaker, or close to it). I've been using Linux continously since around 1998 (well, I did my first install on my amiga 4000 in 1995 using 9 floppy disks, don't remember the distro) and I've been using (not much administration though) Solaris, AIX and HP-UX since around that time as well (at school at work). It seems some developers are hell bent on inventing Windows all over again (this goes not only for udev but also for Gnome and their supporting libraries)... Best regards Peter K I'm a desktop user to and I'm not liking this one bit. Dale :-) :-)

Alex Schuster wrote: Right, I somehow overlooked this, thanks for pointing that out. Dale, if you want to avoid the initramfs, what about moving large stuff like /usr/src to another location and symlinking it? That's a hack, but a small one compared to what an initramfs is :) Wonko I already have portage on a separate partition and I clean out my kernel sources once I get a really good stable kernel. I actually cleaned out /boot and /usr/src last night. The kernel I am running now has let me have weeks of uptimes so I guess it is stable, at least everything works and no random crashes or anything. Well, kpat locks up on me sometimes but that is nothing new. As soon as I see a way to win, it locks up tight. Pisses me off when it does that. lol I got a spare drive in here. I may just do a install there and use it to play with init crap and maybe LVM. Sort of see what I want to do. Still thinking about just picking something else tho. I'm just not seeing the need to continue if options are going to be removed. Eventually Gentoo will be like Mandrake where you just install and say a prayer it works. The things that are going away are the reasons I chose Gentoo to begin with. sighs Dale :-) :-)

Sure, but how much bigger are your kernels actually? root@fireball / # du -shc /boot/ 84M /boot/ 84M total root@fireball / # I get 82M, but I have ten kernels in there. What stuff do you have in /boot? Wonko Well, I *had* several old kernels in there. I save stable kernels as I upgrade until I have a really good one then I remove the older ones. I always keep at least two kernels tho. If one fails, I got a fall back. I have had to use those fall backs before so I won't be changing that policy here any time soon. I think I had about a dozen or so in there until my cleaning out party last night. I also save back up configs to just in case a kernel goes bad or I need to go back. I version my kernels too. Long story. Dale :-) :-)

I think me and Alan are the top posters here so I guess me and him like helping folks. Alan has a lot of server type experience and I have a bit of desktop experience. We may have some overlap there tho. Me, I'm a desktop user and I like to run a distro that I'm proud of. In the past, it seemed Gentoo sort of lead on some things. Now, it seems to follow instead. If I want a distro that just follows, I could have stayed with Mandrake/Mandriva. It follows Redhat if I recall correctly. It also uses the init* stuff too. Which as I pointed out before is one reason I left that. If I got to use one with Gentoo, that just takes one reason for using Gentoo and all the compiling stuff away. Gentoo has some good points but lately, they seem to be getting lost on the point scale. Well, I got divorced once. I just hope reason will pop up and I don't have to shift something important to me again. This would be as bad as me divorcing my ex. Heck, maybe worse. I been using Gentoo long before I met my ex. sighs Dale :-) :-)

Without LVM, you are unlikely to be able to resize / or /usr as it is not usually the last partition on the drive. So, you guys want a separated /usr, but don't want a separate /boot. Awesome. I want as much as possible on LVM, and no initramfs. A small / and everything else on LVM fulfils that need. Again, I don't see the reason for a separated /usr. That doesn't mean there aren't several valid reasons to do so. I didn't say they were invalid, I say that *I* don't see the reason to separate /usr. The arguments exposed just don't convice me. But anyway, you will be able to do it with an initramfs. No one is saying YOU should change your preferred setup. Please do us the same courtesy. Accept that we may have thought quite hard about what we want, what we need and how best to achieve it. How would you feel if you were told that you had to separate /usr, install extra packages, go through extra configuration steps and introduce more points of failure, just to do what you are already doing?

How about accepting the fact, that there are a lot of things out there you don't see? Get over it. People have told a lot of valid reasons. They might not seem valid to you, but that's not their problem. Have you *ever* thought about machines, that are not x86 or x86_64? Here's an intersting read: http://permalink.gmane.org/gmane.linux.gentoo.devel/72769 Change happens. That's right. And sometimes these changes are simply bad ideas. Mounting it read-only seems the only sensible one, and then I think is better to go all the way and mount / read-only. Putting /etc on a read-only filesystem seems a really bad idea. To say the least. It works, and it makes life easier for upstream. Which are the ones writting the code. Hu? There's one upstream writing all the code for all the stuff we use? That's news to me.

You can always remount / in another LVM module. Really, what's so
especial about /usr?
Don't get me started. Oh, wait, you just did.
Right, here goes:
An initramfs is optional becuase i can disable it in the kernel. I
would like to keep that optional.
FHS says I can have /usr on a separate partition and I would like to
keep that because it is a good idea.
FHS says I can mount /usr read-only if I choose, which is also a good
idea. On a shared jumphost with 570 concurrent users it's actually a
VERY GOOD ODEA and I'd rather not lose that facility thankyouverymuch.
I do not need, want nor can I find a valid reason to *require* an
initramfs. Systems boot just fine without them.
FHS says I can have the minimal software and tools to effect a system
repair on / and put then entirety of user-space on /usr. Everything
involved in this thread runs early in the boot process and I fail to
find a single convincing reason why /usr is involved at all. Anything
required at this point can simply be put into /bin, /sbin and /lib{,64}
which one will note is exactly how we have been doing it all along.
This whole mess has every indication of a singular maintainer who
cannot be bothered taking other people's needs into account and
foisting off his own personal preferences onto an entire ecosystem.
I think such people should take note of how Torvalds works and emulate
him as opposed to emulating say Drepper as a role-model for good
project mantainership practice.
