Currently, the up2date-gnome RPM has the "/var/spool/up2date" directory. 
If you are running a server with no GNOME or X, and only install up2date,
it when you try to run it, it will fail.

Traceback (innermost last):
  File "/usr/sbin/up2date", line 394, in ?
    main()
  File "/usr/sbin/up2date", line 377, in main
    sys.exit(batchRun(onlyList, pkgNames, fullUpdate))
  File "/usr/sbin/up2date", line 190, in batchRun
    if totalSize > up2date.freeDiskSpace():
  File "/usr/share/rhn/up2date/up2date.py", line 925, in freeDiskSpace
    dfInfo = os.statvfs(cfg.readEntry("storageDir"))
OSError: [Errno 2] No such file or directory: '/var/spool/up2date'

The fix:

Have the up2date RPM create/supply the /var/spool/up2date directory instead
of the up2date-gnome RPM.
