When `df' is given pathnames as arguments, it implicitely sets the `-a'
flag.  At our installation (of Sun 4's running SunOS4.1.1), the
unfortunately large and poorly maintained `auto.direct' is often out of
date with respect to `/etc/exports' files or even what machines exist.
Checking `ignored' filesystems in this situation produces obnoxious timeout
delays.  This also causes undesirable reports for automounted filesystems:

   > df .
   Filesystem         1024-blocks  Used Available Capacity Mounted on
   ne:(pid129)		...		...	...	   /netshare2

But without the `-a' set:

   Filesystem         1024-blocks  Used Available Capacity Mounted on
   ne:/mnt3c		...		...	...	   /tmp_mnt/netshare2

How about not setting `-a' unless specifically requested:
