Interesting. (BTW, this is running on a GENERIC kernel, no firewall.) I did a packet capture on the OpenSolaris NFS server, and found that the kernel load and initial boot takes place over NFSv2. When the FreeBSD box tries to remount root, it sends a NFSv3 FSINFO request. The server returns NFS3ERR_STALE. It appears that that error is generated when the permissions to the mount are revoked... but we just mounted it seconds before? It turns out that there's a whole discussion thread on nfsv2 and v3 interoperability with diskless systems. See http://lists.freebsd.org/pipermail/freebsd-hackers/2008-January/022792.html for a sample message. Short answer: it seems that there are interoperability annoyances with diskless systems and assorted NFS servers. NFS mount options in /etc/fstab seem to be ignored, but you can set them in /boot/loader.conf. boot.nfsroot.options="nfsv2" made FreeBSD try a NFSv2 remout, and the system came up. Thanks for pointing out it seems to be a permissions error, I wouldn't have headed down this route without that. ==ml -- Michael W.
