I am using dracut to unlock my LUKS2 encrypted rootfs on ARM64 machine. However, generated initramfs is unable to unlock rootfs. The reason for this is that /lib/systemd/systemd-cryptsetup has a dependency on libgcc_s.so.1. This dependency is indirect (via dlopen), not visible in ldd. dracut has a code to deal with this but it relies on libgss_s.so.1 being in libdir. At the moment on gentoo this is located in /usr/lib/gcc/aarch64-unknown-linux-gnu/7.3.0/libgcc_s.so.1 but obviously, this will change as gcc versions change... Normally, dracut uses libdir autodetection and will look at the contents of /etc/ld.so.conf.d/05gcc-aarch64-unknown-linux-gnu.conf which contains this path (/usr/lib/gcc/aarch64-unknown-linux-gnu/7.3.0). However, gentoo ebuild hardcodes libdir in the ebuild. Ebuild installs file /usr/lib/dracut/dracut.conf.d/gentoo.conf with the following contents: libdirs="/lib64 /usr/lib64" Thus libgcc_s.so.1 is not in the libdir path. Reproducible: Always Steps to Reproduce: 1. Encrypt rootfs with LUKS2 2. Use dracut to generate initramfs. 3. Possibly ARM64 machine is necessary. Actual Results: Initramfs is unable to unlock rootfs Expected Results: System boots.

It seems that it was fixed upstream recently: https://github.com/dracutdevs/dracut/commit/f6e777ec4b1031b18b835cd34ed644ebf4a2ace6 But we probably still need to preserve lib -> lib64 symlinks in initramfs. Currently I don't have any SYMLINK_LIB=yes system to test this.
Also, a bit annoyingly, if I remove gentoo.conf with libdirs, some other files are go missing (although, libgcc_s.so.1 is included) Only in 3/lib64: device-mapper Only in 3/lib64: libdevmapper-event-lvm2.so.2.02 Only in 3/lib64: libdevmapper-event-lvm2mirror.so Only in 3/lib64: libdevmapper-event-lvm2raid.so Only in 3/lib64: libdevmapper-event-lvm2snapshot.so Only in 3/lib64: libdevmapper-event-lvm2thin.so Only in 3/lib64: liblvm2cmd.so.2.02 Only in 3/lib64: libnss_dns-2.27.so Only in 3/lib64: libnss_dns.so.2 Only in 3/lib64: libnss_files-2.27.so Only in 3/lib64: libnss_files.so.2 Only in 3/lib64: libnss_myhostname.so.2 Only in 3/lib64: libnss_resolve.so.2

Just deleting gentoo.conf fixes boot.
Note to self: SYMLINK_LIB logic comes from bug 508652.

At least it worked fine before dracut-033-r2 where $libdirs was introduced. :)
