Re: designing a brand new NFS.

Will read up on those specs...

I have no intention of reimplementing NFS exactly. The stuff I'll churn out
(not given it a name yet) will not be compatible with the original NFS in
anyway. I should have written 'a' NFS in my mail; my bad. I chose NFS (the
app this time :-) as a starting point cause it's the most popular and well

BTW, for some strange reason this thread has been hijacked by a discussion
on LILO. Please guys, next time think up a new subject line. Less confusion
all around.
