Has anyone else experienced trouble with hierarchical
mounts using autonfsmount? Did you find a way to make
it work?

1) List the desired mounts in *reverse* order, e.g.:

wuarchive.wustl.edu:/archive/mirrors4 /Net nfs ro,soft,net,intr,timeo=4,nosuid,noquota,retry=2 0 0
wuarchive.wustl.edu:/archive/mirrors3 /Net nfs ro,soft,net,intr,timeo=4,nosuid,noquota,retry=2 0 0
wuarchive.wustl.edu:/archive/mirrors2 /Net nfs ro,soft,net,intr,timeo=4,nosuid,noquota,retry=2 0 0
wuarchive.wustl.edu:/archive/mirrors /Net nfs ro,soft,net,intr,timeo=4,nosuid,noquota,retry=2 0 0
wuarchive.wustl.edu:/archive/systems /Net nfs ro,soft,net,intr,timeo=4,nosuid,noquota,retry=2 0 0
wuarchive.wustl.edu:/archive/usenet /Net nfs ro,soft,net,intr,timeo=4,nosuid,noquota,retry=2 0 0
wuarchive.wustl.edu:/archive /Net nfs ro,soft,net,intr,timeo=4,nosuid,noquota,retry=2 0 0

1a) wuarchive provides erratic service; sometimes the mountd will
    get hosed, and autonfsmount doesn't like this.  It's happened
    to me enough times that I just keep a little shell script
    lying around:

	#!/bin/csh -f
	set verbose
	/usr/etc/ping wuarchive.wustl.edu 56 1
	/usr/etc/rpcinfo -u wuarchive.wustl.edu 100003 2
	/usr/etc/rpcinfo -u wuarchive.wustl.edu 100005 1

    If it gets all the way through without errors, autonfsmount
    should be happy.  If not, I stay out of /Net/wuarchive...

1b) NFS access to wuarchive.wustl.edu can be slow when it's
    heavily loaded.  FTP is usually faster for getting directory
    listings.

2) Don't chdir "all the way down" if the filesystems aren't
   mounted; just go to the uppermost mount point and wait.
   (Walking through the Browser (starting at /Net) is fine, but I
   wouldn't recommend putting a submount on the shelf.)
   Otherwise you tickle a race condition where the interior mount
   fails (presumably from EBUSY on /private/Net/whatever).
