I won't get to it until summer as at the moment outdoor work here is
tolerable, but I plan to go over the entire issue of disk labeling and
partitioning. There are a huge number of what are retrospectively poor
decisions and ancient cruft that needs to be addressed in format(1m).
On consideration, I think gparted should go away and the functionality moved to
format(1m). Of course, that presumes that the OI/Illumos community are still
comfortable with command line tools and do not require a GUI.
I just bought an HP Z840 and will be spending the next month or so configuring
it to build Illumos and OI in preparation for doing a modest amount of serious
work on things that annoy me.
I'm not so old as to have dealt with SMD drives, but I had lots of experience
with the disk geometry and remember format(1m) responding to a 5400 rpm speed
with a "preposterous" error message.
I need to do a *lot* of reading about how modern drives behave with respect to
alignment. At present it appears to me that we have lie stacked upon lie
stacked upon lie. It's time for a bit of truth.
Have Fun!

If anyone gets around to working on gparted (or an alternative) please
consider making it use "megabyte aligned partitions" and ignore
so-called "geometry" (like partition editors do on pretty much every
other OS does now).
