Thanks, Sam.

I "installed into a directory" using YaST (SUSE 9.2).  In this case, I 
took the suggested dir of /var/tmp/dirinstall.

Once that was done, I had to su to root, then I could run 'chroot 
/var/tmp/dirinstall/'

Viola!  I was in a new virtual Linux box, logged in as root, setting at 
the bash prompt, in the new virtual root.

pretty cool, but I still don't know enough for it to be useful.

I was thinking about running that tinyp2p in a chroot jail.  There are 
lots of other things I'd like to have the option of jailing as well. 
Finally, there are things I'd like to be able to do the setup/tear down 
routine until I get the setup part mastered.

Anybody use chroot for anything?
