Re: free space reports

It looks correct on your current run (cfengine reports 18% free and
df shows 82% used, which mactches exactly). Your var does seem
fairly volitile, since its about 300MB larger today thatn a couple of
days ago.  Perhaps you spool a lot of mail or print jobs, or maybe
system accounting files.
