Isn't that waste of space?
I see your /var/ file system is the same size as / file system, so
creating two mirrors (ad4a+ad6a) for / and (ad8a+ad10a) for /var/ will
save you some space.

Nice idea, but I think at this point it is too much specific for you
configuration. It'd be much useful when it will be more general somehow.

Yes, Craig Rodrigues (rodrigc@) is working on it.
