Thanks Doug for your help. I am cc'ing freebsd-questions and I will drop
freebsd-hackers from the next email on.

A few things:
1. it's not a requirement, but I'd like to keep the current partitions
(therefore dual boot) just in case anything goes wrong.
2. can you point me to more readings regarding how I might perform the
following: " However in order to set the new slice bootable you'd have
to then use the disk editor"
3. I guess what you are saying is that if I go with the upgrade path
release 4->5->6, I can do "in place" upgrade over network.

Again appreciate your help.

Thomas

You're not planning to dual-boot anything, right? Just boot and run one 
operating system?

You definitely can't use any of the standard installation methods
without 
console access. You also can't dual boot without console access.

No.

You could theoretically install onto a local system, tar it up, then 
unpack it in the unused partition on your remote machine, yes. However
in 
order to set the new slice bootable you'd have to then use the disk 
editor, and if you get even one thing the tiniest bit wrong, you've 
bricked it.

If I were in your position I'd do this with make world, but that's going

to take a looooooooong time because you'll first have to update to the 
latest RELENG_4, then 5-stable, then 6-stable (at least) and then if you

don't want to have to do this again for a while I'd update to 7.0 when
it 
is released.

The other alternative is to bribe someone who is local to do the 
installation for you, which all things considered would probably be
easier 
all around.

hope this helps,

Doug
