Whoops! Sorry. FreeBSD 4.7.

Hmm. I saw these. In /etc/rc, it checks the value of the
vfs.nfs.diskless_valid sysctl, and if it's non-zero, then
/etc/rc.diskless1 is executed. But how does that sysctl get set? So I
assumed I didn't need to do anything to have /etc/rc.diskless1 run.
More importantly, the job for rc.diskless1 seems to be creating a
mfs-based /etc. I'm mounting the NFS partition read-write, so I figured
this wasn't important.

I didn't create a /conf, because I didn't want a customised /etc per
machine. Also, at this point I am allowing the PXE client to connect to
the gateway NFS export with read-write and -maproot=root

Does this help?
