Hi,
Has anyone here sucessfully used a Netapp fileserver as the NFS root
filesystem for FreeBSD clients?
My FreeBSD client basically mounts the Netapp, boots the kernel, but
fails early in /etc/rc because /dev/mem, /dev/kmem, /dev/null (and
friends) are unavailable.
NOTE that this all works fine when a FreeBSD box is used as the NFS
root server, but everything else being the same. The client is
mounting an image built from -STABLE sources late last week.
Here's what I'm seeing when the client boots -v:

I can provide more boot verbosity upon request. Any ideas as to what
the problem might be?
Thanks,
