Theoretically, yes.  But in his use case, he has config info on the
box as well (users, hosts, maybe his mail spool, etc.).  So he will
need to salvage data from the rpool manually anyway.

If you are in a data center where you have DNS and LDAP, everything is
auto-mounted and nodes are provisioned automatically, then a data-free
rpool is certainly a prerequisite.
