Bug#981666: cdrom-detect: Preseeding cdrom-detect/load_media and a high-enough priority lead to failure
Package: cdrom-detect
Version: 1.92
Severity: normal
X-Debbugs-Cc: j2468h@gmail.com
Dear Maintainer,
Recently experimenting with a rather obscure setup that involves running the installer from a non-cdrom device and preseeding, I've discovered that cdrom-detect doesn't allow cdrom-detect/load_media to be preseeded.
This is caused by debconf returning code 30 if the question isn't shown, this error code should be ignored to allow preseeding, the attached patch fixes the issue.
It has been tested by hand editing the postinst script on a live system, as I don't know how to rebuild the debian installer initrd.
