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.
