UBUNTU: debian -- more agressivly clean up after depmod on purge
BugLink: http://bugs.launchpad.net/bugs/618591
During install we execute depmod to ensure we have the appropriate module
supper indexes for the installed system, we are however required to clean
up after it on uninstall. As depmod is provided by an external package
changes in that package can lead to the kernel leaking files on uninstall,
preventing a successful purge.
Though we cannot know what files depmod does generate they (so far) all
are prefixed with "modules." in /lib/modules/<version>/. The kernel
binary packages do intentionally include two files with this prefix
(modules.builtin and modules.order). As we know exactly which files we
are carrying move to removing all other modules.* files when uninstalling
to ensure we cleanup comprehensivly behind depmod. Also adds linkage
between the two places where these files are now listed to ensure we keep
them in lock-step. This should ensure that should new files be added to
depmod's output set we should purge them automatically.
