On a stable system, I've been using a custom initramfs (root on lvm on encrypted drive partition) since 2008. I've upgraded it's parts a number of times. In december I upgraded to cryptsetup-1.6.2 and lvm2-2.02.103 (both with static USE). Today, I notice that if I try to re-emerge cryptsetup or lvm2, they want to disable the static USE flag.

I checked the ebuilds and saw that static is still a valid USE for both; I checked my package.use ( both set static) and make.conf (nothing)... and I've tried to discover what is overriding the USE I have set in package.use... what changed since my last initramfs build...

How do I determine what it is that is forcing these packages to turn off the static USE flag? :?

Code:
# emerge -av lvm2

These are the packages that would be merged, in order:

I see the same thing here. It could be getting turned off by your profile. For instance, on one of my boxes, I am using default/linux/amd64/13.0/desktop/gnome/systemd. If you follow the parent file, there is a package.use.mask file in profiles/targets/systemd containing:

Code:
sys-fs/cryptsetup static static-libs
sys-fs/lvm2 static static-libs



Maybe you are using a systemd profile or another similar?

I don't use cryptsetup, but I do use lvm and I have seen no ill-effects, but then again I use genkernel. I don't know if genkernel does anything special for lvm in the initrd.

Ok, I've looked at the profile and followed the parent file. I'm using kde desktop, and openrc with USE="... -systemd ..." in my own package.mask. In the profile parents, I see lots of profiled USEs, but I don't see any package.mask type fle that would have turned the static USE off... what am I missing? (still confused :? )

I start in /etc/portage with make.profile -> ../../usr/portage/profiles/default/linux/amd64/13.0/desktop/kde

So I cd ../../usr/portage/profiles/default/linux/amd64/13.0/desktop/kde
Code:
# for i in $(ls); do [ ! -d $i ] && echo "---[ $i ]---------------" && cat $i | grep -v "#" ; done
---[ eapi ]---------------

---[ parent ]---------------

../../../../../../targets/desktop/kde

So I cd ../../../../../../targets/desktop/kde

In my own package.use, I set static for both cryptsetup and lvm2 (and libraries not shown)
Code:
sys-fs/lvm2 static static-libs udev -dynamic
sys-apps/busybox mdev static -dynamic
sys-fs/cryptsetup static -dynamic


Here's the cryptsetup ebuild - don't see it here, either. I do see a comment about non-support for nss, but I don't think that applies because although I have nss on my system, I'm not using it as a cryptsetup backend (as far as I know).

This is bad practice for several reasons. Never use ls to feed other commands. Use [ -f "$i" ] to test if it is a file, since there are unreadable non-directories such as FIFOs and local domain sockets. Never engage in useless use of cat. Use grep -v "#" "$i" to read the file.

With regard to your actual problem, do you need static lvm/cryptsetup? You could instead put the required glibc libraries in the initramfs, then use regular non-static tools in the initramfs.

It's because USE="static" is broken:

http://bugs.gentoo.org/show_bug.cgi?id=496612
http://bugs.gentoo.org/show_bug.cgi?id=520450

Instead of using USE="static", the required dynamic libraries should be copied to the initramfs, like both dracut and genkernel does.

However, you can still unmask USE="static" by file in /etc/portage/profile/package.use.stable.mask

Code:

# mkdir -p /etc/portage/profile
# echo 'sys-fs/crypsetup -static' >> /etc/portage/profile/package.use.stable.mask
# echo 'sys-fs/lvm2 -static' >> /etc/portage/profile/package.use.stable.mask

Bummer.

brendlefly62, maybe the size of the initramfs will be ok for you. Here is what mine have been over time:

ssuominen and russK -- thanks for the guidance. I am working to include the necessary libs in my custom initramfs, and I'll post a "[solved]" update when I get it working ("never give up").

Hu -- Thanks for the lesson:

Better, but still not what I would recommend. Using find is preferred over ls, but your usage is still subject to being confused by embedded whitespace. To demonstrate:
Code:
touch './a b.x'
for i in $(find . -name \*.x -type f); do echo "$i"; cat "$i"; done
To fix, use instead:
Code:
find . -name \*.x -type f -print0 | while read -d '' i; do echo "$i"; done
However, this runs the loop in a subshell, so variables set inside the loop are not visible after the loop ends. If you need this, and can assume GNU bash (instead of POSIX-compatible sh), use:
Code:
while read -d '' i; do echo "$i"; done < <( find . -name \*.x -type f -print0)
