Hi! I had some struggle with a separate /usr on top of LVM and the dracut thing. I noticed that udev was complaining at boot that it could not find some scripts.
The usmount dracut module did not work for me because it could not find /usr. So what I did was to include the fstab-sys smodule in dracut: /etc/dracut.conf # Dracut modules to omit omit_dracutmodules+="usrmount" # Dracut modules to add to the default add_dracutmodules+="fstab-sys" Then I created /etc/fstab.sys with just the /usr partition /dev/disk/by-uuid/90d82b02-e6c2-4011-940e-783d12b0c4fe /usr ext4 noatime 1 2 Dracut could only find the partition by using the uuid (use blkid to find it easily). The next step was to remove /usr from /etc/fstab to prevent /usr from being mounted twice (the boot process does not like it). The last obstacle is /etc/mtab. By the time /usr is mounted I believe / is mounted as read only, so mount cannot update /etc/mtab. The trivial solutions is to delete /etc/mtab and make it a symlink to /proc/mounts . In that case it is always up to date. Of course, YMMV. Be careful when changing things that can prevent your machine from booting and make sure you have a live CD at hand.
