Bug Description
Dapper Flight 2 installs successfully in an UNdocked ThinkPad T42, and installs itself on the internal hard disk, which it sees as hda.
However, when you then dock the same ThinkPad in the ThinkPad Dock II (the one with an additional bay for a floppy or optical drive, etc.), Ubuntu won't boot, because it now sees the same harddisk as hde, not hda.
A similar problem occurs when installing to the ThinkPad in the dock II: the installer sees the hard disk as hda, but when Ubuntu starts up, it sees the disk as hde, and can't complete the installation.
I think this didn't happen in Breezy (though my Breezy setup was different), but it's a major annoyance in Dapper.

I have experienced this too just on a normal desktop machine. It has one HDD connected via IDE1, then 4 160Gb disks on a PCI IDE Adaptor. In breezy the disk was seen as IDE1, but in dapper it's IDE6. The partition (hda2) Dapper thinks should be hde2. Subsequently, I can't boot.
very annoying.
