At home I have 1.5 running on a couple of sparcs, which have no
 trouble doing automounting from a 1.4.2 i386, nor does a freebsd
 machine.

 I'm still no closer to getting it to work on a sparc64 here at work.

amd on sparc64 does have some issues.  I find that it does not
recognize when I change CDROMs.  There are probably some latent
LP64BE bugs lying around somewhere.  However, I have never had any
problems with /net mounts either from the sparc64 box or the
other way around.

 Given the map:

 amd.homes:
 /defaults            type:=link
 *                    fs:=/home/callisto/${key}

 amd.home:
 /defaults            type:=nfs;opts:=rw,grpid,resvport,nodev
 # /home/localhost always points /home/<machine>
 localhost      type:=link;fs:=${host}
 callisto             type:=nfs;rhost:=${key};rfs:=/vol/vol2/homes

 amd.host:
 /defaults       type:=host;fs:=${autodir}/${rhost};rhost:=${key}
 *               opts:=rw,grpid,resvport,nodev

 referencing /homes/sjg/tmp should create:

 /homes/sjg -> /home/callisto/sjg
 /home/callisto -> /.amd/callisto/vol/vol2/homes

 however what I get is:

 ls: /homes/sjg/tmp: Input/output error

 the link /homes/sjg -> /home/callisto/sjg is created ok, but nothing
 is mounted, nor any link created in /home.

 If I reference /host/callisto/vol/vol2/homes/sjg/tmp it works!

 ls -ld /host/callisto/vol/vol2/homes/sjg/tmp
 drwxrwxrwt  9 sjg  software  8192 Jun  7 15:11 /host/callisto/vol/vol2/homes/sjg/tmp/

 local bits work fine:

 ls -l /home/localhost
 lrwxrwxrwx  1 root  wheel  6 Jun  8 15:38 /home/localhost@ -> hobbit

 I've tried using amd.conf to force use of udp, nfsv2 etc etc, the
 result is always the same.  ktrace doesn't show anything particularly
 interesting. 

 Callisto is a netapp btw, but I get the same result with other servers.
 The client is an ultra1:

 NetBSD hobbit.juniper.net 1.5Q NetBSD 1.5Q (HOBBIT) #2: Mon Jan 29 13:51:31 PST 2001     root@hobbit.juniper.net:/u1/obj/sys/arch/sparc64/compile/HOBBIT sparc64

 any clues welcome.

First of all, I have no reason to beleive NIS works (or doesn't work
for that matter) so if you're using that you should test it out first.

Other than that, I would recommend trying to recompile the amd binaries,
and maybe the RPC libs and see if that helps any.
