Description Marco Scardovi (scardracs) 2021-06-24 21:01:21 UTC
Following [1] I have moved from libcrypt to libxcrypt and compilation were all good.
Unfortunately genkernel does not handle -lcrypt on busybox as valide if libxcrypt is used and fails to compile initramfs.

@Whissi and @sam already know about that but opening bug as tracker.

P.S.
Unfortunately I don't have any genkernel.log because it was overwritten by the one made with libcrypt
Comment 1 Thomas Deutschmann (RETIRED) gentoo-dev 2021-06-24 23:30:24 UTC
I tried to reproduce on a fully converted system but failed (which makes sense if new libxcrypt is a drop-in replacement). Furthermore, default busybox built by genkernel doesn’t even link against crypt.

The only failure I was able to force was in util-linux when forcefully deleting libxcrypt headers (=putting system into broken state).

Therefore I am currently suspecting that this bug report is invalid (i.e. problem was seen on a not fully converted system) and requesting full logs (genkernel.log & `energe —info sys-lib/glibc libxcrypt’).

Sorry, the link contain a typo at the end, the correct one is https://gist.github.com/thesamesam/a36ff15235f5cbe5004972f80f254123

This is the failed genkernel running with libxcrypt

Comment 5 Thomas Deutschmann (RETIRED) gentoo-dev 2021-06-25 15:37:44 UTC
Only happening when system uses sys-libs/libxcrypt[-static-libs]. Note that glibc is forcing static-libs and libxcrypt has USE=static-libs by default enabled.

    defaults/software.sh: Add libxcrypt
    
    Needed for BusyBox when host system is using sys-libs/libxcrypt[-static-libs]
    which is usually enforced via package.use.force.

This is fixed in 4.2.3, I think?
