The following commit has been merged in the debian-next branch:
commit cf5a1d2db470818386314a9f1752264e83077592
Author: T(A)ILS developers <amnesia at boum.org>
Date: Wed Oct 20 18:33:12 2010 +0200
Enhancing devices search ordering.
E.g. prefer mounting /dev/sdb1 rather than /dev/sdb.
The isohybrid feature makes both valid devices for being searched for a live
filesystem image. Previous code mounted /dev/sdb on /live/image which makes it
hard to create a second partition on the USB stick.
This brings the need to explicitly check whether the full device is in the
blacklist before even considering its subdevices: the previous blacklist
checking code worked because the full device was always considered before its
subdevices, which is not true anymore.
