NFSv4 without portmapper ?

[Gabriel Barazer]

Hello,

I am testing the nfs utils (not patched for now) on a clean system (in 
fact it's a kind of linux from scratch). I wan't to write a bootscript 
designed to start _only_ the nfsv4 server or a nfsv4 client (without 
support for nfsv2/3). Since nfsv4 is designed to operate on only 1 TCP 
port, is the portmapper still required ? The 2 only services needed must 
be rpc.idmapd and rpc.nfsd, but starting rpc.nfsd appears to hang:
rpc.nfsd command line is :

rpc.nfsd -N 2 -N 3 -U -p 2049 8

strace-ing it show the locations where rpc.nfsd hangs :
