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 distributions. This little script tells me where I'm running from: #!/bin/bash # /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 $bid) ; rstr=${rline#*\"}; DIST=${rstr%%\"*}; unset bid rline rstr; else DIST=$( e2label $(mount | grep " / " | cut -d" " -f1 ) ); fi The various partitions are labeled for the Debian version. This may or may not help you but works for me. Have fun, Mike -- "Beauty without grace is a hook without a bait." - Ninon de Lenclos
