Ops: We'd really like to split the Irix 6.3 /os volume up into more pieces.
This mail gives more information. Comments?

There are currently six AFS volumes which compose the /os hierarchy,
which uses symbolic links to keep the number that small and to keep the
volumes from being over 500M.
To eliminate the symbolic links would cause us to either wind up with
some volumes much larger than 500M, or result in more volumes. Going
the route of just replacing all of the symlinks with new mountpoints
would add six volumes, for a total of twelve. Alternatively, we could
only replace some of the symlinks with mointpoints and the rest with
directories, resulting in a few more volumes and a couple of larger
volumes.
The reason I did it the way I did was I felt uncomfortable pushing
even the six volumes on operations to deal with, and I hadn't thought
of the relative symlink problem at the time. When I did discover it, I
ran a broken program which indicated there were only a dozen or so
relative symlinks to worry about. In fact, there are 1079 of them. So
at this point I too would be much happier if we could split /os into
more and/or larger volumes. Otherwise, maintaining the volume from a
development standpoint is going to become very irritating and error
prone.
