If "options NFSD" isn't in your kernel config, I think you'd have to get nfsd.ko loaded before setting the sysctl and do both before starting mountd. I don't know of a clean way to do this? Putting kldload and sysctl command lines in mountd_precmd() in /etc/rc.d/mountd would do it I suspect. Maybe rc variables for this should be added? (I haven't tried this since the only kernels I have handy have "options NFSD" in them.) rick > >> Maybe it was the talk about getting rid of the oldnfs stuff that > >> made you think V2, 3 were going away? > Yes, that was it and I obviously misunderstood that thread. > > What's the max NFS version that supports mount_root from PXE clients > then?
