[Bug 1496672] [NEW] casper check_dev bind mount directory when?

[Jay Michael]

Public bug reported:

     initramfs-tools/scripts/casper function check_dev will bind /cdrom
to the "device" being checked if it is a directory (and contains a
filesystem.squashfs file).

     When will that "device" ever be a directory?

     Bug #230716  seems to have introduced the code

if [ -d "${devname}" ]; then
   mount -o bind $devname $mountpoint
   if is_casper_path $mountpoint; then
     echo $mountpoint
     return 0
   endif
 fi

     What I don't understand is what "devname" could be that it could be
identifying a directory, other than a directory in initrd (initramfs?),
which couldn't contain the live media.
