  Excellent!  I've made a note of it.

  I use two-spindle mirrored rpools for boot/swap and /usr/local on
every Solaris system I manage.  Everything else goes in a separate
raidz1 or raidz2 pool, depending on requirements.

  That figures.

  I'm only running T-series machines now, but I may investigate 11.
I've been on 10 for many years; things are rock solid so I am reticent
to move.  Perhaps I'll set up a test machine.
