[p4] NFS mounted depot

[Smith, Jeff]

The problem is that they told me something different.  And what they
told me is inconsistent:

"You should absolutely be wary of using NFS!  If you care at all about
[...] the integrity of your data you will keep these files on a local
disk."

and later in the same email:

"NFS locking [...] will work [but] it will not work as well as it can
and it will be subject to more problems than a local implementation
will."

Which seems like a contradictory statement.  None of this has any
bearing on the problem which is that their documentation states that no
part of your server installation should be accessed via NFS unless using
Solaris 2.6.  Our concern is that with such a strong statement in the
official documentation, we are wary of the support we would receive
should anything go wrong with such a setup.

But I understood from an earlier post that Perforce had already told you
that the archive files are OK on NFS disks (as long as the other stuff
isn't)??
