Bug#250349: Usability: CD-ROM related issues

[Frans Pop <aragorn@tiscali.nl>]

Package: debian-installer
Version: 20040513
Severity: minor

1. Abort installation should unmount CD-ROM
===========================================
If you select "Abort the installation and reboot" during a CD based 
installation, the CD-ROM is not unmounted. This means the CD can not be 
ejected before the reboot takes place and thus the system again boots from 
the CD, which may not be what you want.
I don't think automatic ejection (like with "Finish the installation") is 
necessary, just unmounting should be enough.

Note: the unmount should be for both /cdrom and /target/media/cdrom0.

2. cdrom-checker
================
If you run "Check the CD-ROM(s) integrity" at the end of the installation 
procedure (just before reboot), cdrom-checker will leave the CD unmounted 
for /cdrom after it has run because the CD_ROM is also mounted on /target/
media/cdrom0. This causes all sorts of problems.

/target/media/cdrom0 should probably be unmounted at the start of 
cdrom-checker (and maybe remounted after the "Insert Debian boot CD-ROM" 
dialog?).
