Hello!

These BootEinvironments are *very* handy when you get into trouble after 
some crude pkg fiddling.
On Linux installations you are in a mess if something severly happened,
with the BE on OI/Illumos and FreeBSD now (i think)
you just choose the previous BE and destroy the corrupted one later - 
easy-peasy.

It would allow selectable installations of OI with different package 
selections on one root pool
- if you think you need to and take care and set the BE names when doing 
something with pkg.

I love it.

:-)
