Description danny 2007-04-19 10:20:11 UTC 
removing a file from the read-only  / NFS mounted partition hangs
the client, this is due, because the mount is NFS/V2.

How-To-Repeat: mount_nfs -2 host:/<some-ro-file-system> /mnt
rm /mnt/somefile

as far as i know nfsv2 had been decprecated, use v3 or v4 instead. If 
you can reproduce it with that please let me know so that I can update 
the ticket with more (better) information.

kris claims that this does need to be fixed.
Comment 3 danny 2007-12-21 10:57:16 UTC 
I found a undocumented feature: boot.nfsroot.options="nfsv3" that  
fixes this problem
So I think this PR can be closed, but would be nice to document  the  
fix, or better, maybe
make it (nfsv3) the default mount in nfs_setup_diskless.

There is a workaround for this problem, perhaps we can investigate whether the suggestion can be implemented?
