FreeBSD7.2 + Debian testing ("Squeeze") dual boot

[AG]

Hello all

I've been tempted for quite some years now to try FreeBSD, so I am 
wanting to dual-boot the most up-to-date version (which I *think* is 
7.2?) with Debian (cn: Squeeze) on an AMD Sempron Dual Core 2300 sata 
machine, with a Debian configuration on /home.

This is a project that I am going to be playing with over the next few 
months, so know that I have lots of reading to do, and the calibre of 
FreeBSD docs looks impressive.  Kudos.  At this point, I'm just wanting 
to do a bit of straw poll about these systems playing together, 
especially around the UID on /home/* and whether that poses a problem 
accessing the same files from different OSs?  Just interested in general 
thoughts and opinions, if people are cool with that.

Thanks

Anton
