Do you mean that it is sleeping instead of suspended?
In the STAT column of ps, a 'S' means 'sleeping'.
Look at the 'ps' man pages.

I think you are right.

Be sure that the file '/etc/services' in the target includes the following
entries:
  sunrpc   111/tcp   portmapper   # RPC 4.0 portmapper TCP
  sunrpc   111/udp   portmapper   # RPC 4.0 portmapper UDP

Also, be sure you have the file '/etc/rpc' present in the target.

This is a script, so it does not need to be compiled.
The only thing you need is the interpreter (first line in the script).
That script invokes the Bourne Shell (usually accomplished by bash).
The script should be invoked at the command line, giving it a parameters.
Valid parameters are: start, stop, restart, reload and status.

This is a good approach. The files seem to be correct.
(BTW, I think the rpc file comes with the glibc distribution).

I guess it died, even after successfully registered with the portmapper.
Here are some ideas I have to verify everything.

1) Does it produce a core file?

2) You may start mountd with the following options:
     mountd --debug all --foreground
   This will start mountd in foregroud, turning on debugging information.
   I hope it will help...

3) You may also start the syslog daemon, to be sure you don't miss important
information.

4) Also, is the file /etc/exports present?

5) I see that the nfs startup script performs a 'exportfs -r' before
starting the daemons.
   Could it help?

This is correct, since the port number is assigned randomly, unless you use
the command line option '-p' to force mountd to bind to a specific port. The
rpc port number should be identical, and correspond to what is in /etc/rpc.

The mountd process (rpc port 100005) is not in the process table, because it
unexpectedly died, even if the registration still appears in the portmap...
as if you kill mountd with a SIGKILL (9) :-(

Good luck!

Well, of course, I meant 'ifconfig', not 'ipconfig'.
I can't remember where this mistake comes from... ;-)

> but your hint is correct only in one direction:

Sorry, I stopped reading further... ;-)

To be able to export and mount you target's /, enabling the kernel option is
needed but not enough.
You need the portmapper (portmap), NFS daemon (rpc.nfsd), NFS mount daemon
(rpc.mountd).
I'm not sure, but you may also need the remote quota server (rpc.rquotad).
Of course, you should have a valid /etc/exports file.

All this comes from the standard NFS control script.
Refers to the nfs-utils package (http://sourceforge.net/projects/nfs/)
in the script file 'etc/nodist/nfs-server'.
You can even use it directly to start the NFS server.

The portmapper (portmap) and the lock daemon (rpc.lockd) are not running on
your target.
Either you start them, or just add option "-o nolock" when calling mount.
  # mount -o nolock -t nfs 126.126.126.106:/home /tmp
