Hi,

I was reading 'man nfs' but realised that is only userland nfs-utils. Doc for 
nfsroot is at:
/usr/src/linux/Documentation/filesystems/nfsroot.txt

Apparently nfsroot defaults to nfs2 , unlike mount nfs (at least on recentish 
2.6 kernels).

I added the right parameters to the "exec" kernel command line given to redboot

exec -c "console=ttyAM1,115200 ip=192.168.1.50 
nfsroot=192.168.1.3:/back/nfs,rsize=0,wsize=0,nfsvers=3,proto=tcp"

this gets me vers3 and a much more responsive nfs system, no need to add a line 
to fstab.

To recap most of the mad erratic behaviour I was seeing before was due to nfs 
not playing nicely with reiser4. This is basically an untested config as far as 
nfs (Sun) are concerned.


Thanks for all the help.
