[OpenAFS] mountpoints are always RW...

I thought this was it... root.afs hadn't been replicated... Except now 
even with root.afs replicated it is still accessing the RW copy...  And 
I've been though all levels & checked, and ALL volumes are replicated... 
Is it as simple as the caching clients need restarting once the replicas 
have been made (Reboot still is it?) Or a timeout needs waiting on?

What puzzles me is that I can't do an lsmount on /afs itself... It says 
it doesn't exist... e.g.

root# fs lsmount /afs
fs: File '/afs' doesn't exist


Is it possible to explicitly mount the .readonly copies o fthe volumes 
under /afs/cellname/mumble and the read/write copies under 
/afs/.cellname/mumble and force the behaviour I want (i.e. no update on 
the clients till I release), or is that too gross a hack to consider?
