Thanks for the updated patch Brian, and apologies it's taken so long to
review.

I've had a quick look through, and generally it looks fine to me.

On utilties? here, I wonder if the name for this option could be
clearer? Most of the other options can be interpreted in the context of
the filesystem itself, but this is about whether the system profile
should include utilities for that filesystem. I haven't got any
particularly good ideas though, maybe system-include-utilities?

I think utilities? is OK though, if someone wants to turn it off, then
they'll probably be able to work out how. On that, maybe the only must
before merging this is adding to the list of options in the
documentation. Is this something you're able to do?

Thanks,

Chris
