[Tux3] Tux3 and virtualization

[Daniel Phillips]

Tux3 and server virtualization will go very well together.  You create
one root volume image for all the servers, then take a snapshot of it
for each server instance.  Each server can then make changes to its
version of the root filesystem, and each server can furthermore make
snapshots of its snapshot for the purpose of replication or backup.

A virtual environment like UML can let the virtual server directly
mount the Tux3 filesystem on the host, while virtual environments
without such capability would have to loopback mount a single file
of the Tux3 host filesystem, which would be the root volume image.

Note that ddsnap can already do this.  The likelihood is that Tux3
will be able to do it more efficiently, at least until similar
algorithms are backported into ddsnap.

Regards,

Daniel
