Comment(by mungewell):

 For Ubuntu based systems:
 It is convention to include an info file in the '.disk/' directory of the
 LiveCD;
 ---
 $cat .disk/info
 Ubuntu 8.10 "Intrepid Ibex" - Release i386 (20081029.5)
 ---

 Whilst running the CD will be mounted under /cdrom, so look in
 '/cdrom/.disk/info'

 This unfortunately won't help if you are creating the live disk by adding
 an additional squashfs archive to an existing CD. I'm not sure whether you
 can overwrite a file, or know which order the squashfs archives will be
 loaded.


 The other problem is that a LiveCD/USB is actually a full system, given a
 large enough persitance file one could actually update the whole system to
 a newer release of the distribution (just an 'apt-get' away).

 So an activity might actually be a newer release than that on the
 LiveCD/USB image/distribution.

 The only sure fire way is to dump the package lists.... 'dpkg --list'.

 Cheers,
 Mungewell.
