I doubt that day will ever arrive. subslots are a way for devs to tell portage that the condition revdep-rebuild detects can happen, and to rebuild stuff as part of the emerge. So what happens if the subslot is wrong or missing in the ebuild? Portage can't detect that and humans leave such stuff out all the time.

The usr-merge will be a slow, gradual change; it will probably take years. The systemd package entered the tree in June 2011, after more than a year in an overlay, and then it took more than two years to make it an official alternative to OpenRC. The /usr merge will take a similar amount of time, if not longer. Yes, but systemd is a large important package and it requires changes to startup files in other packages, so, it took a lot of time. As the opposite, /usr merge is easier and, IMHO, it doesn't introduce any _obvious_ problems to Gentoo. 2013/8/16 Daniel Campbell li...@sporkbox.us Red Hat is only upstream for GNOME and systemd. What they choose to do with their distro should not affect the choices of any other distro. I see no reason for a /usr merge unless one is using Fedora or wants to turn their Gentoo installation into a makeshift Fedora installation. This merge should not be forced on Gentoo whatsoever. I would like to ask you to understand my intension. I believe that Gentoo is a distro that is famous for providing choises (USE flags and so on). /usr merge is also a choise, and I look for volunteers and supporters. BTW, /usr merge is not just a Fedora's caprice: is is done in Arch this year: https://mailman.archlinux.org/pipermail/arch-dev-public/2012-March/022625.html Sincerely, Alessio Ababilov Senior Software Engineer Grid Dynamics

[gentoo-user] emerge -e errors right after install
Hello, all. Gentoo is absolutely great. This is mainly to make clear I am pretty satisfied on how things are made to let us have a Linux distro that does not use binary packages, everything being built almost from the ground up. But (here comes the but), right on the point I was able to build the kernel (I'm using the live CD from 08/01/2013 for x86_64 machine, and a stage 3 tarballl from the same date for the same machine), I tried an emerge -e world, and there were so many errors that very few packages were able to be completely built. Mainly the errors are at the end of the config stage, and they are like: ... config.status: creating Makefile ./config.status: line 1091: 26891 Done(141) eval sed \\$ac_sed_extra\ $ac_file_inputs 26892 Illegal instruction | $AWK -f $ac_tmp/subs.awk $ac_tmp/out config.status: error: could not create Makefile ... or ... configure: creating ./config.status config.status: creating install-info/tests/defs ./config.status: line 1218: 31166 Done(141) eval sed \\$ac_sed_extra\ $ac_file_inputs 31167 Illegal instruction | $AWK -f $tmp/subs.awk $tmp/out config.status: error: could not create install-info/tests/defs ... or, like xz-utils, that complained that it was unable to create a Doxyfile, even having a I have built binary packages for sed and gawk, created in a machine with the same characteristics and configuration, and emerged those to the new machine. Even so, the errors keep coming. Am I too anxious? I did not see anything further in the documentation that could help this situation, so even not having finished all the installation procedure, I think it should be possible, at this moment, right before building a kernel (but after a few pages, right before section 9. Installing Necessary System Tools). In fact, it seems like there is one (or some) package(s) missing. Thanks Francisco

So what does this mean for those of us with older systems with separate /usr and don't want initramfs? It means exactly what the Council voted: Since that particular setup may already be subtly broken today depending on the installed software, Council recommends using an early boot mount mechanism, e.g. initramfs, to mount /usr if /usr is on a separate partition. If you don't want an initramfs, you are on your own. Things will start to break subtly (probably they *are* broken *now*, you just didn't noticed), and if you file bugs about it they will be closed as WONTFIX or INVALID. If you want your system to be supported, you need an initarmfs, or anything similar that allows the system to mount /usr really early in the boot process. https://wiki.gentoo.org/wiki/Early_Userspace_Mounting http://www.gentoo.org/doc/en/initramfs-guide.xml By a quick lecture of the Council session, I believe they are even open to a closer /usr merge than I thought. When that happens (if it happens), your system (if you keep upgrading) will not be able to boot for sure if you don't follow the Council suggestion.

If you have physical access to the system, and a large enough /, it's really easy. You boot from a livecd, mount /usr in another directory, copy all the files from it to /usr (be sure to preserve links, permissions, attributes, etc.), change /etc/fstab, and off you go. If you need to resize / then it's a little more difficult, but not so much. You need again to boot with a livecd, and somewhere (a external or internal disk with enough free space) to put the contents of / and /usr while repartitioning an reformatting the drive that contains them. Afterwards you just change /etc/fstab and you are good to go. If it's a remote system then it gets hairy; any changes to how /usr is handled should not be done while the system is running. And really, maybe you could try an initramfs? It will be much more easy than any juggle of filesystems.

Yeah, basically. And really, maybe you could try an initramfs? It will be much more easy than any juggle of filesystems. I always compile my kernels manually, by choice - so, no desire to use genkernel or dracut. I compile my kernels manually too. Since ever. Dracut generates an initramfs from your running system, is orthogonal to compiling your own kernel. How would I then create one? I am *not* a programmer, just a reasonably competent general sys admin. Is there a 'generic' one that I can use? Or is there a separate tool that will create one based on my system profile (or whatever)? Yeah, dracut. Emerge dracut with LVM support, adding lvm to DRACUT_MODULES in /etc/portage/make.conf, then edit /etc/dracut.conf, and add lvmconf=yes, and run dracut like this (for example): /usr/bin/dracut -f -H /boot/initrd-3.10.7 3.10.7 Then you add an initrd line to GRUB, or GRUB2 will automatically detect the initrd with grub2-mkconfig. You should at least try it before changing partitions; is so much easier. If it fails, you can still do the integration of /usr and /.

Is there a 'generic' one that I can use? Or is there a separate tool that will create one based on my system profile (or whatever)? I think dracut is actually exactly the tool you are looking for. It does not have anything to do with building your kernel, its sole job in life is to generate an initramfs built to your specifications. It contains sane defaults but you can tweak it to include or exclude things as you see fit. I build my kernel by hand and then run dracut afterward to generate the initramfs.img. I believe mounting /usr is enabled by default in dracut. I would recommend checking out the documentation and seeing all the different options and modules that are available so you can customize it to match your needs. For example you may want to have it import your LVM configuration, assemble a RAID, use the reiserfs or btrfs filesystem, etc. Once it generates the initramfs it's as simple as adding a line to your grub config and off you go. If it doesn't work right away you can just comment out that line and boot without it, for now, while your existing setup is still valid. (It took me a few reboots to find the right combination of options.) Then someday if separate /usr is no longer allowed without an initramfs, you'll be prepared for it. I always regenerate my initramfs using dracut after every time i build a new kernel, but I'm not sure if that's truly necessary. Honestly it's all still a bit of a black box to me.

The first one lost it's file, the second one kept it. I've got a couple more t update so I'll see if I can see a pattern.

I have the following in make.conf
CFLAGS=-O2 -march=native -fomit-frame-pointer -pipe -fno-unwind-tables
-fno-asynchronous-unwind-tables
CXXFLAGS=${CFLAGS}
...where -march=native will always work correctly for a local build.
The only possible worry is if you're cross-compiling and or distributing
a binary to multiple machines. It also saves me the headache of
figuring out the CFLAGS setting whenever I get a new machine. You still
have to set up the correct processor in the kernel, however.

In Python 3 print is a function, and should be called like this:

This works as-is in Python 2, unless you have this at the top of the

Thanks Keith, that was suggested on the ceph list but grepping doesnt
show it in the source. With this version of ceph they have replaced the
ceph binary with a python script so its quite different from the older
version which works. They target mainly centos and ubuntu/debian so I
will have to keep looking.
Have you tried a simple:
python3 /usr/bin/ceph
Regards.
No, doesnt work either. The ceph guys say it works fine for them which
leaves me suspecting something is broken on my system ...
BillK
Still not sure if I have a bug or a broken system.
1. If I use eselect to set python 3 and build ceph from the ebuild
it wont work
2. If I eselect python 2.7 it wont work
3. if I rebuild it with python 2.7 selected it now WORKS - yea!
4. if I eselect python 3.2 it wont work :(
Ok, I am suspecting that something in ceph isnt playing nicely with the
gentoo eselect system and having python2 and python3 on the system :(
I guess its pulling in something python2 when 3 is active which is where
the __future__ mechanism comes into play.
So next question is ... can I remove python2? - last I heard, portage
needs python2 and wont run properly with python3 - is that still the case?
