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.

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

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

You could theoretically install onto a local system, tar it up, then
unpack it in the unused partition on your remote machine, yes. However
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
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
The other alternative is to bribe someone who is local to do the
installation for you, which all things considered would probably be
