One last netbooting issue

[Christopher Wagner]

Maybe have an icon on the desktop that sync's things, then you can hard
power down, or modify the shutdown scripts to not TERM processes, or just
have it selectively TERM processes.

The boot floppy is set up with the kernel parameters:
root=/dev/nfs nfsroot=130.157.139.237:/netboot ip=dhcp

I would think that that would do it.

Hmmm.  I don't have control of the DHCP server, so I can't be sure whether
or not it'll try any on-the-fly stuff.
If the kernel itself is auto-configuring the network as described above,
should it even need dhcpcd to be running?

I can't get away with read-only access.  Imagine someone spending a class
period writing up something in AbiWord or KWord, and then getting a
"read-only filesystem" error when he or she clicks on "Save"!
