retitle 810748 systemd does not mount /usr in initramfs, breaking split /usr reassign 810748 systemd 215-17+deb8u2 severity 810748 serious
If I read the code correctly, than this patch is the culprit: http://sources.debian.net/src/systemd/215-17%2Bdeb8u2/debian/patches/Skip-filesystem-check-if-already-done-by-the-initram.patch/?hl=29#L29 When systemd is run in the initramfs (which it is with dracut), there is no /run/initramfs/fsck-usr. Setting severity to serious because split /usr with initramfs is supposed to be a supported setup. Please adjust if my assessment is wrong.
