On my ULTRIX-based workstation the directory /usr/spool is linked to
/var/spool. On most UNIX-machines the /var directory is part of the
root ( / ) filesystem (Not on my ULTRIX-stations, where the /var-
filesystem is a separately mounted partition). I think SunOS will
use a similar layout of spool-directories, because the /var-filesys.
contains machine-specific-files, which can not be shared on a network
between multiple machines. But the /usr-filesystem contains primarily
files which can be shared for saving diskspace.
