Software RAID-1

[Chris Hastie]

I'm looking at building a FreeBSD server with two identical 60GB hard 
drives configured with software RAID-1. What would be the best way to 
set about this? Vinum or RaidFrame (which it appears from release notes 
/ errata doesn't work on 5.1) or something else? And what is a sensible 
procedure to get something like this working on a fresh install?
