I agree that it would be nice to have a better way of
automatically detecting the size and geometry of disks for our Suns.
I'm not sure this would be an easy thing to implement, though.

It's my opinion that you're overstating the complexity involved
in creating a new partition table for a new species of disk. As one of
the people who's added a lot of the new disks we've gotten recently, I
can say it's less than 30 minutes of work, worse case scenario, and the
work I did for Lou this evening took much less than that. This isn't to
say that we shouldn't make the process more efficient, but it isn't like
walking over hot coals now.
