ppc NFS Server issues

Hi all,
I'm having a problem trying to nfs mount directories on my target
system from my host. (i.e. target running nfs server)
I'm running an embedded planet mpc860T board. (Hard-Hat linux,
journeyman cdk v1.1). I boot up with an
initrd filesystem which I put together myself. In a nutshell,
I can mount the target volume on my host, but then attempting to
ls it, I get messages like: (/e is my mount point)
ls: /e/bin: No such file or directory
ls: /e/var: No such file or directory
ls: /e/proc: No such file or directory
I had to build some stuff from the RedHat 6.2 SRPMS:
nfs-utils-0.1.6.tar.gz
portmap-4_0-19_src.rpm
tcp_wrappers-7_6-10_src.rpm (portmap needed libs from these)
I managed to cross-compile portmap, nfsd, mountd, and exportfs
from these with very minor hacks. (In particular, nfsd, mountd, and
exportfs
only needed me to remove the tools dependency (which built a ppc version
of rpcgen and then tried to run it on my pentium)
portmap printed out a lot of dangerous-looking warnings (like illegal
pointer-type kind of messages) but did compile.
All these programs run without complaining on my ppc target.
2 Questions:
a) Am I going in the right direction? I compiled my kernel with nfs
server support, etc. Do I need portmap, mountd, and nfsd? Or is there
a way to replace some of these with built-in kernel support? Do I
need some of the other programs (like lockd?)
b) Anyone have an idea what's going on here? Am I totally stupid
to cross-compile RedHat 6.2 SRPMS and expect them to work? Do I need to
comb through all the warnings and decide whether they're benign?
The remainder of this is information gathered to diagnose the problem.
Thanks,
Mark Phillips
(A few curious things...
Note that the uid for portmap is 1, while everyone else's is root?
Why do some ps entries get bracketed while others do not? (This is the
busybox ps)
Why doesn't rcpinfo show the names (like portmap, mountd, nfsd?)
