Bug#341383: lilo-installer fails to find LVM group

[MeDon <xmedeko@gmail.com>]

Package: lilo-installer
Version: 1.14
Severity: normal


(Architecture i386)

Hi,

I have my own script to partition disc. It create a root LVM volume
/dev/lvmsys/root and mout it as

mount /dev/lvmsys/root /target

However, lilo-installer assumes that an LVM volume is mounted as

mount /dev/mapper/....

So, the function lvm_vg () in postinst does not recognise that root is
mounted on LVM (in my case). I've chenged lvm_vg() to

lvm_vg () {
  # Map from /dev/mapper/<vg>-<lv> to /dev/<vg>/<lv> for
  # Dup of code in partman.
  vglv=${1#/dev/mapper/}
  if [ "$vglv" != "$1" ]; then
    vglv=$(echo "$vglv" | sed -e 's/\([^-]\)-\([^-]\)/\1 \2/' | sed -e 's/--/-/g')
    vg=$(echo "$vglv" | cut -d" " -f1)
    lv=$(echo "$vglv" | cut -d" " -f2)
    lvdisplay -c "/dev/$vg/$lv" 2>/dev/null | cut -d: -f2
  else
    lvdisplay -c "$1" 2>/dev/null | cut -d: -f2
  fi
}

and now it works OK for both cases.
