Hardy release notes should mention device name changes

[Marius Gedminas]

Recently I helped a friend upgrade an old 6.06 (Dapper) server to 8.04 (Hardy). The system was using software RAID-1. It did not boot with the new (hardy) kernel: complained about being unable to find the root device (/dev/md0) and gave an initramfs shell.

After a few hours of banging heads against the wall we realized that Dapper detected the two hard drives as /dev/hda and /dev/hdc, while Hardy detected them as /dev/sda and /dev/sdb. To get a bootable system we had to edit /etc/mdadm/mdadm.conf, replace the device names in there and rebuild the initramfs image with dpkg-reconfigure linux-image-2.6.24-24-server.

If it's impossible to seamlessly upgrade systems using software RAID, at the very least the upgrade notes (https://help.ubuntu.com/community/HardyUpgrades) should mention that this sort of manual change may be necessary.

Is this still a relevant release notes request? The bug is marked as affecting two persons in *hardy*, but we're about to release the next LTS (lucid) now, so I'm not sure we want to add a release note on the previous LTS for apparently a relatively low impact issue?

Thanks,
