Besides, in a virtualized environment this assumption is
not hard to live up to.
As a slight but related digression, has any thought been given to
using something other than /dev/[hs]d* names for specifying block
devices? The name /dev/sdb only has meaning for the current
state of the running dom0 OS. It may not mean the same device
on a different dom0. This can lead to problems in say migration.
In fact, it may not be the same when the domain is restored locally.
Having to configure all the possible migration targets to see all
the same devices in the same order at all times is not realistic.
In a dynamic environment it would be ideal to make a device visible
to the target dom0 only as it was needed to migrate a given VM to
that dom0. Naming it /dev/sdb may not be a possiblity in this case.

Phil
