Description Michal Schmidt 2013-10-19 08:24:54 UTC
After upgrading to dracut-034-18.git20131018.fc20 my system does not boot. Regenerating the initramfs with the previous dracut build (dracut-034-8.git20131008.fc20) fixes the problem.
My root filesystem is on an LVM logical volume.
A diff between the working and the broken initramfs shows this suspicious hunk:

- rd.lvm.lv=nonraidvg/swap rd.lvm.lv=nonraidvg/F-root
+ rd.lvm.lv=nonraidvg/swap nonraidvg/F-root

This line seems to be generated by the looped touched by the fix for bug 1013767, so I suspect that this is what caused the regression.
(Seems that "$line" now contains all the values from get_host_lvs at once, instead of being assigned one after another in the loop.)

As a workaround I can add "rd.lvm.lv=nonraidvg/F-root" to the kernel command line and boot successfully.

I'm unable to reproduce this in qemu/kvm:
1. Boot Fedora-Live-Desktop-x86_64-20-Beta-TC5.iso, and install using guided partitioning default (conventional LVM); and reboot.
2. yum update dracut
3. dracut -f
4. reboot.

System does reboot.
