There seems to be several common problems with user of NFS on the
Risc System/6000:

1. Cannot mount older NFS servers (servers running with pre SunOS 4.0 NFS)

2. NFS ACL operations not supported on server xxx: RPC: Program unavailable

The first problem is that by default root is in more than 8 groups.  Older
NFS servers had a bug which caused them to only accept 8 groups.  This was
a violation of the protocol spec (see RFC 1057).  Changing root to have 8
or fewer groups will fix this problem.

The second problem is not a problem, but an informational message.  The
AIX file system supports Access Control Lists.  There is a special RPC program
running on AIX NFS servers to allow NFS clients to view/change these lists.
The message is there to inform the user (only happens on the first access
attempt of a newly mounted FS) that the "aclget", "aclput", "acledit", etc
commands will not work on this NFS filesystem.
