dummy's guide to emulation?

[Carl Brewer <carl%bl.echidna.id.au@localhost>]

Hello,
I want to try and replace a SCO box (OS 5.0.5 I think, it's old and 
hairy) with something modern for a client, I've given up on xen, VMware 
etc to run SCO in, it's just too hard to get SCO working in a VM.

Anyway, NetBSD seems like it can emulate SCO, but is there any doco on 
how to set up an environment such that an application that looks for 
things in certain places finds them?  Is something like a big chroot 
environment suitable?  Is there some magic that the emulation layer does 
to help?  Things like printers etc? Or simple things like where to find 
database files and the like?

Any pointers to a beginner's guide to using emulation in NetBSD much 
appreciated!

Thankyou

Carl
