Something that converts things automatically to whatever?  That's not been done in more than one year.  It's not acceptable to update, reboot and not find the root file system no matter what.  We all agreed on that back then.  I do not really care how it's done.

For the record, it would seem that Alexander did not provide any
follow-up to this message, but still decided to go forward. I would be
interested to have his answer to your question.

Thanks,

> b) FYI: labels and stacked geoms do not work well together as you can never detach providers cleanly then, which basically means you are at risk of data loss with every reboot.  I was told multiple times that this is not fixable.  If it is labels seem to be a great why to go.  For now I have to compile them out/disable them unfortunately so they are not an option, and they'll be less so if the new installer also offers gmirror, geli, ... installs.
