Bug#508906: [initramfs-tools] Doesn't detect LVM for root=/dev/dm-X
Package: initramfs-tools
Version: 0.92l
Severity: important
--- Please enter the report below this line. ---
Let me start with some additional relevant info.
The root fs is located on LVM and is described in
/etc/fstab with LABEL= notation, which leads
to the following mount output for root filesystem:
> mount | grep "on / "
/dev/dm-0 on / type ext3 (rw,noatime,errors=remount-ro)
> e2label /dev/dm-0
ROOT
The /dev/dm-0 itself isn't a symlink to /dev/mapper/, therefore root var
remains /dev/dm-0 after readlink -f attempt.
> ls -l /dev/dm-0
brw-rw---- 1 root disk 254, 0 Dec 15 15:46 /dev/dm-0
All this consequently leads to failure in detecting the LVM root.
Please let me know if any additional info is needed.
