Thank you so much, that got rpc.statd started! NFS is still not behaving 
quite right, unfortunately. The /etc/fstab file:

# /etc/fstab: static file system information.
#
# <file system> <mount point>   <type>  <options>    <dump>     <pass>
10.208.108.18:/tftpboot/oscar  /  nfs 
rw,rsize=8192,wsize=8192,nfsvers=3       0       0
proc            /proc           proc    defaults        0       0
10.208.108.18:/usr  /usr  nfs  rw,rsize=8192,wsize=8192,nfsvers=3 
0       0
/dev/fd0        /floppy         auto    defaults,user,noauto    0       0
/dev/cdrom      /cdrom          iso9660 defaults,ro,user,noauto 0       0
10.208.108.12:/home      /home   nfs 
rw,rsize=8192,wsize=8192,nfsvers=3,nosuid,nodev,async 0       0
10.208.108.12:/lab       /lab    nfs 
rw,rsize=8192,wsize=8192,nfsvers=3,nosuid,nodev 0       0

But, this is not how things are being mounted:
root@oscar:/# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/hda1              19G  854M   17G   5% /
tmpfs                 1.9G     0  1.9G   0% /lib/init/rw
udev                   10M   64K   10M   1% /dev
tmpfs                 1.9G     0  1.9G   0% /dev/shm
df: `/tftpboot': No such file or directory
/dev/hda6              19G  854M   17G   5% /tmp
/dev/hda7              33G   11G   21G  34% /usr
/dev/hda2              19G  854M   17G   5% /var
rpc_pipefs             19G  854M   17G   5% /var/lib/nfs/rpc_pipefs
10.208.108.12:/lab     19G  854M   17G   5% /lab
10.208.108.12:/home    19G  854M   17G   5% /home

For some reason, it looks like things are being mounted locally, even 
though they cannot be (no local hard drive). The /lab and /home 
directories are actually not being mounted, they are empty. And all of 
the directories appear to be read-only.

If I try to remount, I get this:
root@oscar:/# mount -a
can't create lock file /etc/mtab~2820: Read-only file system (use -n 
flag to override)
root@oscar:/# mount -an
mount.nfs: /usr is busy or already mounted

It does not appear to even try to remount /lab or /home, and /  is still 
read only, even if I try to mount it by hand:

root@oscar:/# mount.nfs 10.208.108.18:/tftpboot/oscar / -v -rw -n -o 
rsize=8192,wsize=8192
mount.nfs: trying 10.208.108.18 prog 100003 vers 3 prot TCP port 2049
mount.nfs: trying 10.208.108.18 prog 100005 vers 3 prot UDP port 44350
10.208.108.18:/tftpboot/oscar on / type nfs (rsize=8192,wsize=8192)
root@oscar:/# touch /tmp/test
touch: cannot touch `/tmp/test': Read-only file system

Any ideas would be appreciated.

cheers,
maria
