The big thing is the ensure that locking works.  Ensure that files
accessed both via NFS and via SMB are correctly locked.

This is best done by ensuring that you use the latest Samba 2.2, Linux
Kernel 2.4 and the appropriate libc (2.2 I think) this will gain you
access to the 'kernel oplocks' that will allow cooperative locking
between the two protocols.  You may wish to follow the discussions on
this list, becouse there have been some 'issues' with this that are
currnetly being looked at.  (Possible bugs in the linux kernel oplock
implementation I beleive).
