After a recent dist-upgrade, I failed to mount /boot when rebooting. Further investigation shows that /dev/disk/by-path has an entry for my /boot as /dev/sda (rather than sda1). Updating to use the by-id in /etc/fstab solves the problem, but I'm curious what changed and if this is a known issue. I would guess that this is an issue with changes in either udev or the kernel.
The partition table is a Sun disk label, which means that /dev/sda1 starts at sector 0 and the filesystem header thus starts in the same place as if there were no partition table. I believe on my e450 that this is in fact required for the boot partition, so I don't know that there's an easy fix in the installer aside from defaulting to one of the by-id options.
