Hello Dick,

What you mean by "remote boot" is evidently "root filesystem on NFS",
just to be sure we are talking about the same thing.

Sure, it can work, if you accept all the insecurities implied by that
setup, I mean that all file I/O traffic is
 - sniffable
 - forgeable
that may be no problem if you trust more or less _all_ on your network.

If you mean root filesystem on Coda, then no (well, mostly "no way")

If you mean starting Venus at system startup, I guess most of systems with
Coda do it :-)

Again, you mean "root on NFS", don't you?

We have several hundred NFS-clients that stop working if one NFS server
goes down (no root on NFS, just plain software and user files placed on
It is considered acceptable given investments in the server computer with
all the hardware redundant except the system bus, and the "instant"
on-site service if something breaks.

Not that I like it, but it works.

You are welcome. :-)
