Multiple rootfs's in single server?

[Kaj Wiik]

Hi!

We have a mixture of AMD64 and i386 ubuntu workstations and I'd like
to upgrade/install them using FAI. Is it possible to have multiple
rootfs in a single server? If yes, how the selection will be done? I
guess classes are defined after booting from rootfs. I am starting to
learn FAI, so I am sorry if this topic has been covered already (I
tried to read through the guide and search this group).

Thanks,

Kaj
