Hi,
This works for me, see comments below!

maks, can you comment on this patch. I've attached the full hook
for context. Maybe you'll find other cases that need to be handled
in a special way.

Aside: I think this may be fragile (literal tabs), using [:white:]
would be better. Indeed, grep piped to AWK is often redundant (as AWK
will parse the line again, and has its own POSIX RE support). Indeed
AWK has, what I would consider more comprehensible way of writing
this (tested along with the patch):
rootdev=$(awk '$1 !~ /^#/ && $2 == "/" { print $1; exit }' /etc/fstab) || true
+# Map LVM devices in the form of /dev/vg/lv to /dev/mapper/, otherwise
+# initramfs won't initialize them.
+link=$(readlink -f $rootdev)
+if echo "$link" | grep -q "^/dev/mapper/"; then
+ rootdev=$link
+fi
+
# Translate LABEL and UUID entries into a proper device name.
if echo "$rootdev" | grep -q "="; then
a=$(echo "$rootdev" | cut -d "=" -f 1)
This works fine for me!
Thanks very much!
