Of course I realize that. It was a question aimed to ease/streamline the
upgrade process. Get/install userland now, fix the bloody ownership and
permissions of drbdadm and friends _again_ so they work with heartbeat
(hello package maintainer :-p). And then do the happy dance of 
failover a->b, restart a (well, reload module), failover b->a, restart b
at an opportune moment.
