Package: cdrom-detect
Version: 1.29
Severity: wishlist
Tags: patch
Hi,
In Debian Live, integration with the Debian Installer works perfectly with
ISO images; cdrom-detect mounts the live image containing the installer
components and proceeds with the installation.
However, on USB/HDD images, cdrom-detect naturally fails to locate the
partition on which the d-i components reside, as it is neither an ISO9660
image nor contained on a block device returned by `list-devices cd` or
`list-devices maybe-usb-floppy`.
The attached patch rectifies this by additionally detecting vfat and ext disk
partitions masquerading as Debian CDs. We only concern ourselves with these
filesystem types as well as restricting the search to partitions as live-
helper will only generate images with these combinations.
Regards,
