[Starcluster] problem with centOS ami?

I built a centOS that is supposed to replicate most of the starcluster
ubuntu ami features.

Everything seems to be working fine, except that during the start, get the
following error message (or something like it)

....
>>> Configuring NFS ....
ERROR: ssh.py - 249 : "mount -t rpc_pipefs sunrpc /var/lib/nfs/rpc_pipefs/"
exited with error status 32
...

Even though I see this error, the resulting cluster seems to work fine (my
EBS volumes are shared via NFS, my SGE is working fine ... &c)

Additionally, when I try to re-run the offending command on the master node
directly, after startup completes, I get:

[root_at_domU-12-31-39-0E-40-72 ~]# mount -t rpc_pipefs sunrpc
/var/lib/nfs/rpc_pipefs
mount: sunrpc already mounted or /var/lib/nfs/rpc_pipefs busy
mount: according to mtab, sunrpc is already mounted on
/var/lib/nfs/rpc_pipefs

Justin, do you know what is going on, and how I should fix it? Are things
actually essentially working, or not?

The image is ami-74b65c1d, and I've made it public.


Thanks!
Dan
