SUMMARY: Standard NFS mount point location?

Consensus was that there is no "standard" for where to create mountpoints.
This response from Alan contained a bunch of good info that seems worth
passing on:

        In the right circumstances, any file system will fill up.
        Some are just more sensitive to it than others. One affect
        to consider when picking a location is the affect it will
        have on file name lookups when a server is down. Directly
        off the root, the filename lookup will probably block waiting
        for that particular server to respond. Out of the typical
        directory search, and it won't get touched. For example,
        with a bunch of NFS mounts under /mnt:

                /mnt/this-host
                /mnt/that-host
                /mnt/some-other-host

        /mnt will be searched just fine, even if one of more of
        the hosts are down. But, move each of those up a level
        and the search blocks at each one that is down. Now,
        an ls(1) or pwd(1) that has to go through traverse /mnt
        will be in just as much trouble, that's much less common
        than having to traverse /.

        My advice is, use a mount point that is most natural for
        the file system. Archive or large data spaces, I typically
        hang under /mnt. User file systems, I put on /usr/users.
        It just depends on the data and the "name".

Thanks to the many of you who replied.
