chroot

[Mike McClain <mike.junk@nethere.com>]

I have two different but fairly complete versions of 
Debian installed on separate partitoins on my computer
Sarge on hdc1 and Etch on hda1. If from Etch I chroot
into Sarge then execute some command 'ls' for instance.
Which 'ls' is being executed, Sarge's or Etch's and how 
can I see which is running?

TIA,
Mike
