NFS is in the Linux kernel as of 2.2, AFAIK. <deity> knows why.
At least it explains why Linux has more syscalls than any other
unix. Don't start me of the fact that there's a web server in
the kernel as well.

I actually read the NFS source (in addition to the boot scripts).
It should be a set of daemons, it appears to be heavily woven into
the kernel. Go read the lockd source if you want a laugh.

I know how to set up NFS. Go do a search for "lockd" info
on the LDP. No howtos, no man pages, no "info". Very typical
for Linux: implement first, document second (if ever).

If the reboot command actually worked on this system, I wouldn't.
Since lockd appears to be broken (and is connected to the kernel
somehow) shutdown / reboot doesn't work.

# shutdown -y -g0 -i6
{wait 5 minutes, terminal program never receives a TERM | KILL
signal, but machine stops responding... wait five more minutes..
THEN power cycle system.}
Of course if Linux was "Real Unix" we'd have something other
than beta quality FS journaling and the whole point would be moot.

You're not actually supposed to call reboot (or halt) directly.
Go read the man pages yourself.

Wow! Really! :) Shame x86 hardware doesn't have a proper serial
console implementation, or <gasp> a service processor.
And to think I'd been turning of my Sun E10000 systems by pulling
out all 8 power cords!

Since I can only connect to the machine via a network
(it's at a remote location, I did mention that) it's
probably a safe assumption that I have a network connection.
