/cdrom was only obsoleted in etch by a combination of prayer and wishful
thinking. apt-cdrom still relied on it until very recently, when
Michael Vogt did some work on it. It now has the ability to find CD-ROM
devices using libudev, but some tweaks were needed to d-i to cope with
that. I committed one extra piece to apt-setup, to make sure that
/proc, /sys, and /dev are mounted in /target when running apt-cdrom
since otherwise it will be unable to find devices using libudev.
Perhaps I have missed something, but Frans' changes seem quite
incomplete to me. base-installer bind-mounts /target/cdrom, and
configures apt-cdrom to use it; surely that needs to be adjusted if you
want to do the detection dynamically there as well, and removing the
umounts from most other places while keeping the mount in base-installer
looks like a mistake.
If you don't bind-mount /target/cdrom in base-installer, how do you
ensure that we use the same CD for base installation as was used to boot
the installer? While it's a corner case, it's come up in the past when
somebody had multiple CDs inserted. I would prefer to keep this
facility rather than breaking it, although it doesn't matter whether
it's done using /target/cdrom or some other path.
