Bug#591330: live-snapshot fails to sync at reboot/shotdown

[Luigi Capriotti <l.capriotti@xbmc.org>]

Package: live-boot
  Version: 2.0~a16-1

Use of live-snapshot is currently broken due to an inconsistency in 
parsing snapshot information stored in /etc/live.conf.

snapshot info stored with:

http://live.debian.net/gitweb?p=live-boot.git;a=blob;f=scripts/live;h=a17eb423fca132f0aaf03c8ca6f956766eaef797;hb=HEAD#l1052

and parsed with:

http://live.debian.net/gitweb?p=live-boot.git;a=blob;f=bin/live-snapshot;h=08e5fd654adf08609dc9d7a411da83fc58b3f3a1;hb=HEAD#l245

Similarly on debian-old-1.0:

http://live.debian.net/gitweb?p=live-boot.git;a=blob;f=scripts/live;h=cbec764a9ceeb73f0e6875f5efd54e4ed4bf5cc6;hb=refs/heads/debian-old-1.0#l1176

vs
