Binary package hint: partman-base

(Ubuntu karmic, alternate install CD)

If you manually partition a large disk (2TB or more), a GUID partition table (GPT) will automatically (and silently) be used.
This means that you *have to* create a BIOS boot partition ( http://grub.enbug.org/BIOS_Boot_Partition ), or the grub setup will fail and the system will be unbootable.

There *really* should be a warning about a missing BIOS boot partiton (just like there is a warning about the missing swap partition, which is far less important).

This will bite a lot of people as disks > 2TB become standard.
