.. but it looks like the difference with unison is that with rsync you
do to some extent keep track "manually" of what has changed (at least
what parts of the filesystem) .. since you exclude (include) directories
(etc.) .. while unison as I understand it is capable of detecting what
files (or even parts of files?) need to be copied over automatically.
Incidentally .. as regards my other questions .. cf. "objectives of
debian live" .. I eventually ran - quite by accident - into a short page
that defines them quite nicely.
http://www.google.com/url?q=http://wiki.debian.org/DebianLive/Why&sa=X&oi=smap&resnum=1&ct=result&cd=7&usg=AFQjCNHdgOO5Hkx6dN2F4KJWXahdXO7Rkg
.. or google for "debian live manual" & the first link listed is "Debian
Live Project" and then a bunch of other links under that including one
that says "Why Debian Live" that provides a list of excellent reasons why
one should choose debian live over "exotic" live CD frameworks.
Only thing that worries me a bit is that it would appear to suggest that
only debian kernels are supported .. not stuff that I may have patched
myself.
Thanks!
