There is a bug in the 4.1 mount command that prevents the machine from
mounting NFS filesystems from non-Sun machines.  The relevant Bug IDs are
1040275 and 1036952.

Sun has fixed this bug in SunOS 4.1.1.  For those who need the patch now,
however, it is available from Sun support (refer to the two bug id numbers
listed above).  Or, you can ftp the patch from my machine,
zerkalo.harvard.edu [128.103.40.201], in the file /pub/mount.4.1.patch.Z.

Here is the README file that comes with the patch:

=== Cut here ===

Kewords: mount
Synopsis: sun client cannot mount a filesystem from a non-Sun system under 4.1

SunOS release: 4.1

BugID's fixed with this patch: 1040275, 1036952

Architectures for which this patch is available: sun3, sun3x, sun4, sun4c

Obsoleted by: 4.1.1

Problem Description:
    A Sun machine running SunOS 4.1 cannot mount a file system exported from
    a non-Sun machine.  The error message is something like:

             mount: non-Sun:/filename server not responding
             RPC program not registered

    But, on the same local net the Sun machines running SunOS 4.0.3 are 
    still able to mount the same non-Sun remote file system without any 
    problem.

=== End here ===

Note that the "fix" Sun implemented simply consists of backing off to a
slightly previous version of mount.c:

zeraklo% strings /usr/etc/mount.4.1 | grep '@(#)'
@(#)mount.c 2.93 90/01/08 Copyr 1985, 1989 Sun Micro
@(#)mountxdr.c 1.19 89/06/20 Copyr 1984 Sun Micro

zerkalo% strings /usr/etc/mount | grep '@(#)'	# The patched version
@(#)mount.c 2.91 89/10/05 Copyr 1985, 1989 Sun Micro
@(#)mountxdr.c 1.19 89/06/20 Copyr 1984 Sun Micro

Hope this helps somebody out there.
