Building a server TODAY; which version?

[Brett Glass]

I'm putting together a server that must be up and running
by midnight (old one is failing and most be taken down).
The old one is running FreeBSD, so to make it easy to
replicate the configuration I'd like to put FreeBSD 4.x
on it as well. But which version? 4.8-RELEASE with
patches? 4.8-RELEASE-p13? 4.x-STABLE? or is 4.9-RELEASE-RC2
good enough to consider using? Opinions appreciated.
