Never mind that question. I've been able to reproduce the problem and the
cause turns out to be a script error in grub.
You should be able to boot your system by editing the kernel line for grub
(you can do that from the grub menu) and change
root=
to
root=/dev/mapper/<VG-name>-<LV-name>
If you do not know what the correct path is, boot the installer in rescue
mode and check the device for / in /target/etc/fstab.
The following patch for update-grub will fix this problem.
convert_kernel26 ()
{
# skip /dev/mapper/ from conversion
if ! echo "$1" | grep -q "^/dev/mapper/"; then
echo "$1" | sed 's%^\(/dev/[^/]*\)/\(.*\)%\1!\2%'
+ else
+ echo "$1"
fi
}
