[Voyage-linux] Using a 'standard' voyage image on many remote boxes

[Kim-man "Punky" TSE]

Hi Beat, Rasjid and all,

I would love to hear the idea and possibile enhancement for voyage linux 
in managing upgrade.  Multiple partition sounds one possibility.  I have 
no problem to incorporate any good idea in voyage.  Please discuss here, 
if you have any good insight.

Rasjid, feel free to update the wiki.
