Facing a similar problem of several distributions on one machine I
took a different approach.
I use a separate partition for data '/mc' accessable from all
This little script tells me where I'm running from:
# /mc/bin/set_dist set the variable DIST 071512 Mc
# source this file and DIST will transfer to the calling file
# which distribution (based on partition label)
if [ $(grep -c UUID /proc/cmdline) -gt 0 ]; then
bid=$(cut -d'=' -f4 /proc/cmdline | cut -d' ' -f1);
rline=$(blkid | grep $bid) ;
unset bid rline rstr;
DIST=$( e2label $(mount | grep " / " | cut -d" " -f1 ) );
The various partitions are labeled for the Debian version.
This may or may not help you but works for me.
