When the Debian Installer Netinst ISO is booted from a USB stick and

I contend that partman should have a sanity check to avoid overwriting
the installation media, so that a more useful error message can be
presented to users indicating the lack of usable drives.
I had opened a merge request against partman-base [1] to skip a drive if
mounted on /cdrom or /hd-media, but put it on hold after considering
that it might break some (admittedly edge) use cases. Maybe that check
should apply only to automatic partitioning ?
