Not a real bug, but a suggestion.
When installing on a blank drive, we have to run twice InstallAROS, and that's not so bad. Issue arise when the user creates a single partition at the first round, but then he/she selects to use the DH1 partition for Extras and Development on the second round (after first reboot).
Normally, a wise installer should disable the option to use a non-exsisting partition.
May that option be grayed-out, when no DH1 partition is available? Making this error and having dozens of "insert DH1 drive" messages during installation is easier than you may think! ;-)
