Everything i keep reading tells me that NFS4 does not need portmap but
for some reason on the NFS server ( CentOS 5.x ) i cannot get the nfs
services started unless portmap is running first.
On the server i modified /etc/sysconfig/nfs with the following options
MOUNTD_NFS_V1="no"
MOUNTD_NFS_V2="no"
RPCNFSDARGS="-N 2 -N 3 -U"
For some reason if i uncomment MOUNTD_NFS_v3="no" i get errors.
On the client, again a CentOS 5.x machine but with a newer custom built
kernel, If i do not start portmap then when i run mount it takes about 2
minutes for the filesystem to mount and i see the following messages in
/var/log/messages
Oct 26 10:25:30 host kernel: rpcbind: server localhost not responding,
timed out
If i start portmap, the mount command completed in a few seconds.
My goal here to is run/support NFSv4 Only.

I think you are running into a known problem of when the v4
server comes it uses some legacy code that blindly does
"unregister all my previous existences" to rpcbind.
So that unregister hangs for a bit if rpcbind is not
running... This was fixed in later releases...
