/cdrom should be the default location for the CD and the installation
process should set that up in the fstab acordingly. During
installation all available devices could be checked easily and the
files used to detect the right CD in dpkg-multicd can be used to
detect the drive as well.

I´m working on an autosense and CD find script that scanns /proc/pci
to detect what modules for ide or scsi should be used and scans for
the right CD there. The script is for my "Demo-Linux" filesystem that
boots directly from CD or any recognised filesystem. The according deb
package should appear within this week (before university starts
again) but I need a sponsor for it.

Booting over NFS is an option of my "Demo-Linux" filesystem. The
Network will autoconfig/test itself. Should work find if dhcp or some
Win is running somewhere.

Hmm, when using tftp the Network should be configured already and a
ping to broadcast should show all hosts on that network segment. From
that list the DNS can be guessed, tried or selected and then the
nfs-server can be selected via a whiptail dialog.

I would realy like that. That way you can test a Debian CD before
burning it without the need to wipe an ide drive to simulate the CD.

Doesn´t apt do that already? or what do you mean?

debconf should be in base.

And is exaclty whats needed for the base installation.
May the Source be with you.
