It was because emerge told me it needed it for some reason. It is very rare that I just put something in package.use on my own. This was probably required by some script for mounting /usr or by some initramfs you were using before you switched to dracut. Dracut is pretty advanced by initramfs standards. It handles dynamic linking just fine (bundling libraries/etc as needed). Simpler initramfs tools and such don't, and to make things easier there is a tendency to build anything needed to mount root/usr static so that it is certain to run correctly. You can look inside an initramfs by doing the following: mkdir /tmp/ext cd /tmp/ext zcat /boot/initramfs-3.18.9-gentoo.img | cpio -i find usr find lib64 ... There is quite a bit of dynamic linking going on in a typical dracut initramfs, and quite a bit of stuff installed in /usr it utilizes either to mount root/usr or just for operator convenience (it is nice to be able to use less in an emergency shell, and so on). It is also really easy to tell dracut to add stuff to an initramfs. I tweaked my btrfs module to add btrfstune to the initramfs so that I could easily enable skinny metadata without a boot CD. In some sense, you could think of an initramfs as the rescue CD you always have ready (though I also keep systemrescuecd handy on a USB stick). -- Rich

An initramfs is just a root filesystem. init is /sbin/init unless the kernel is told otherwise. If you took your entire root filesystem, compressed it into a cpio archive, and put that in grub as your initramfs, then your entire distro would run from a ramdisk and you might not even notice the difference (well, assuming you had enough RAM). The only real magic with an initramfs is that it mounts your real root somewhere, then swaps it out for the real root: http://manpages.courier-mta.org/htmlman8/switch_root.8.html This is a bit like chroot, but the old root filesystem is deleted in the process (so that your initramfs does not consume any RAM once the system actually boots). I'm not sure exactly how dracut does it with systemd, since my understanding is that during shutdown systemd actually pivots back to the initramfs (which allows all filesystems to be cleanly unmounted instead of merely being mounted read-only). -- Rich

other package is limiting the highest version. The above is the only one.

Do you have lvm2 built with USE=static?

you get from this:

With a modern initramfs (dracut, and possible recent genkernel), shared libs work just as well, so there should be no need. Well, in package.use, it has some output of emerge that said it needed. Here is a snippet: # required by sys-fs/lvm2-2.02.109[static] # required by @selected # required by @world (argument) #=sys-apps/util-linux-2.24.1-r3 static-libs You are reading it wrong. That means: util-linux needs to be built with USE=static-libs because lvm2 is already built with USE=static None of which explains why you originally built lvm2 that way. # required by virtual/udev-208-r2 # required by @selected # required by @world (argument) #virtual/libudev static-libs # required by virtual/udev-208-r2[gudev] # required by @selected # required by @world (argument) #virtual/libgudev static-libs There's a couple more but you get the idea. I don't use genkernel, tried it but never got a working kernel from it so I do them by hand. Everything built OK with no more complaining so I guess whatever it is has changed. Still weird tho. This has nothing to do with genkernel. More than likely, you followed some daft advice on teh intarwebz saying you need a static lvm to be able to boot / on lvm. -- Alan McKinnon alan.mckin...@gmail.com

Very few people can figure out what they are trying to say. Every once in a while, I get lucky and can keyword a package or something and get past a blocker but sometimes, it may as well spit out Greek characters. Well it's because I understand data structures as used in programming. Things like linked lists and assoc-arrays/dictionaries/hashmaps. I'v also had to support enough programmers over the years and get their stuff to work so I know how their minds work. It's like anything else, if you do it in your line of work, you get to understand it after a while :-) What gets me on this one, it really didn't give a clue what the real problem is. If it did, I missed it. To help folks out, I'll walk through the thought process: The give-away was that util-linux needed to be downgraded, this is very unusual. I figured it was so unusual that finding out why would show me your real problem. And it wasn't a case of the version you have has been removed from the tree. I knew that the only thing that can trigger a downgrade is a DEPENDS that requires some version or lower, and that must start with a or =. So I searched your mail looking for and there was only one :-) This one: sys-apps/util-linux-2.25[static-libs] required by (sys-fs/lvm2-2.02.109:0/0::gentoo, installed) That's the only line in the entire output that can downgrade util-linux. I looked in the lvm2 ebuild and there's only one DEPEND on sys-apps/util-linux-2.25 and it is only used when USE=static After that the rest was easy I just wonder, is there some way they can make emerge spit out something that makes sense or is that something that can not be done? I'm sure there is a way to do it. Some portage output is very useful, like conflicting USE. Portage tells you what you can enable or disable to proceed. And the colorized arrow-heads one line below is really helpful in following version numbers. But proper output messages isn't just a case of translate gobbledy-gook into English. One has to understand what the conditions mean, parse the data portage has inside, and then figure out something meaningful. That is not easy, and probably requires custom code for each different kind of error. Programmers hate writing error code that has to do that, which is probably why no-one has ever done it through portage's entire life so far -- Alan McKinnon alan.mckin...@gmail.com

Looks like this is the source of your problem. When dealing with
blocking downgrades I like to search for the character to find what
other package is limiting the highest version. The above is the only one.
The DEPEND for lvm2 looks like this:
RDEPEND=${DEPEND_COMMON}
...
=sys-apps/util-linux-2.16
...
DEPEND=${DEPEND_COMMON}
static? (
selinux? ( sys-libs/libselinux[static-libs] )
udev? ( =virtual/libudev-208:=[static-libs] )
sys-apps/util-linux-2.25[static-libs]
)
Do you have lvm2 built with USE=static?
Second question is why will portage not upgrade lvm2 for you? What do
you get from this:
emerge -pv lvm2
This lead me down a path. Here is the info you requested:

Here's your problem... there's a virtual/eject-0.ebuild that can be
satisfied by any of 3 different ebuilds, as per the line...
RDEPEND=|| ( =sys-apps/util-linux-2.22 sys-block/eject sys-block/eject-bsd

Any one of them satisfies the virtual, but as the movies say,
there can only be one. To solve your problem...
emerge --unmerge sys-block/eject
emerge -1 sys-apps/util-linux
emerge -uvaDN world
Comments;
1) You must specify sys-block/eject on the unmerge, so it doesn't
unmerge virtual/eject instead. (That's a different kind of
OOPS programming G)
2) manually emerge -1 sys-apps/util-linux so that util-linux gets in
ahead of sys-block/eject to satisfy virtual/eject.
I thought you were on to something but the version is different, which
seems to make emerge behave different. I added -t this time. Maybe
that will help.
