With a separate /usr, we needed to use either fstab-sys or usrmount dracut module to mount /usr before pivot into new root. But if we use usrmount, everything are fine (detection,fsck) but when it attempt to mount it, there is error: "dracut: mount: can't find /sysroot/usr in /etc/fstab or /etc/mtab" Reproducible: Always Steps to Reproduce: 1. Generate an initramfs with usrmount dracut module 2. Reboot Actual Results: Get this error: "dracut: mount: can't find /sysroot/usr in /etc/fstab or /etc/mtab" Expected Results: Mount /usr into newroot before pivot To get what entry usrmount module insert into /etc/fstab, I done a cat on it. And it reveal this line /dev/mapper/vgroot-lvusr /sysroot//usr ext4 0 1 It is almost fine, if there isn't a double slash into mountpoint. Replacing the line echo "$_dev $NEWROOT/$_mp $_fs ${_opts},ro $_rest" by echo "$_dev ${NEWROOT}${_mp} $_fs ${_opts},ro $_rest" in the file mount-usr.sh of usrmount dracut module do the work.
What version of sys-apps/util-linux do you have? I've tried multiple slashed in a mount point (in /etc/fstab) with 2.20.1-r1 and mount doesn't have problem with recognizing it.
I have sys-apps/util-linux-2.19.1-r1
Indeed. I have reproduced this with 2.19.1-r1. I will probably have to depend on newer version of util-linux, since it is the "mount" command broken in this regard.
I have changed dependency to >=sys-apps/util-linux-2.20. This is actually what upstream requires. Thank you for the report!
Please make usrmount module optional instead of forcing usage of ~amd64 util-linux and sysvinit. I have amd64 stable system without separate /usr, dracut works fine.
Dracut requires >=util-linux-2.20 as of Oct 21. My oversight I haven't updated this dependency with version bump to 014. And this is not only because of usrmount. Please use 013 until util-linux-2.20 will become stable.
