Of course I tried that, and it did _not_ work! I'm not sure why, but it was when running a 8.0-RELEASE userland on a 8.1-RELEASE kernel. (I was trying = to run 'make installworld' after booting in single user mode during the upgrade process). After booting with the old 8.0 kernel it did work! > Alternatively, before switching to the ahci driver, label all your=20 > partitions and mount them using their labels rather than device names. This is probably a better idea. But people should note the difference between using 'tunefs -L' and 'glabel label'! The latter uses the last section of t= he provider to store metadata, so in that case one should _only_ create a filesystem on the labeled device! =20 > That way the change in device names won't matter.
