I just upgraded my desktop system from 7.3 to 8.1, and the main hard

The desktop system is now fixed, but I also have a rented server with
only a serial console, and I worry that the upgrade is going to leave me
with a dead machine. Is there any way to predict how the drive number
changes? (Why does it change at all?) If so, what's the proper way to
tell the system the initial root device *before* rebooting?
you may try to label your slices/labels and mount /dev/label/root
instead of /dev/adXsYa
see
man 8 glabel
