Hi,

Recently, I've been playing with booting a 5.0-CURRENT FreeBSD-sparc64 
machine via tftp/nfsroot.  The problem that I encountered was that the 
machine was unable to lock files in it's / nfs-mounted partition, and 
thus I would miss a large amount of functionality (such as having users :))

divine# passwd
Changing local password for root
New Password:
Retype New Password:
passwd: could not lock the passwd file: : Operation not supported

My NFS server is a 4.7-RELEASE machine running the following daemons in 
order to perform NFS:
 portmap
 nfsd -u -t -n 4
 mountd -r
 rpc.statd
 rpc.lockd

According to release notes for 4.7, server-side NFS locking is supposed 
to be functional.  5.0-DP2's release notes say that client-side as well 
as server-side locking is functional.  So in theory, I should not be 
having the above issues.

Does anyone have a working setup with NFS locking tested and working? 
 Can anyone offer any advice on this?

Sincerely,
Anthony Volodkin
