The host is a Debian Lenny, but I can backport some packages if needed. What would be your suggestions? - libguestfs? (I see an unstable debian package existing) - ...? Misaotra, Thanks, Merci. -- Architecte Informatique chez Blueline/Gulfsat: Administration Systeme, Recherche & Developpement +261 34 56 000 19
