Hi folks,

For developing and testing user-space applications (not kernel-specific
code), you can actually have multiple "Linux distros" installed on a
single system and then use them *simultaneously* (without rebooting!) to
do builds and run tests.  Its a very cool chroot trick that I learned
from the folks developing OpenNMS.

For details, see:
