Dusty, all:
So I did an upgrade-and-rollback test today, and the results are kind of
alarming: I can't rollback.
Basically, on a minnowboard, with the current release, if you upgrade,
you are forced to pave and re-install the system to restore it to operation.
OK, less alarming now.
A cold reboot (power off) allows you to roll back to the prior release
and log into the system. For some reason, a hot restart does not.
Somehow, changes are being cached for the boot sector or grub? Or
something?
