Package: initramfs-tools
Severity: normal

Similar to #582858, however for me it still does not work.

When I set MODULES=dep, root cannot be found as the root mountpoint
device does not start with '^/dev/' (thanks to my symlinking /etc/mtab
to /proc/mounts I also get two /'s also):
---- output of 'mount' ----

----

This is trivially resolved by amending the routines that search for the
root block device and fstype in /usr/share/initramfs-tools/hook-functions
to the following instead:
----
# findout root block device + fstype
eval "$(mount | awk '!/^rootfs / && / on \/ type / {print "root=" $1 "\nFSTYPE=" $5; exit}')"

# On failure fallback to /proc/mounts if readable
if [ -z "$root" ] && [ -r /proc/mounts ]; then
        eval "$(awk '!/^rootfs / && / \/ / {print "root=" $1 "\nFSTYPE=" $3; exit}' /proc/mounts)"
fi
----

This filters out the useless '^rootfs' entry (enabling embedded folk to
continue symlinking) and permits anything (not just '^/dev/...') as the
root device.  Now the ubifs root filesystem detection functions.

It should also be noted, the original 'failure fallback' does not work
anyway as it incorrectly refers to $5 (over eager cutting and pasting it
seems) when it should refer to $3 for FSTYPE.

Cheers
