We (i.e. openSUSE/Novell) do no longer use resmgr "inside" SANE
since a longer time.

If no one else uses resmgr "inside" SANE, all resmgr related
code could be completely removed from SANE.


FYI:

Our sane-backends RPM changelog contains:
----------------------------------------------------------------
* Mon Sep 11 2006 jsmeix at suse.de
- disable-resmgr-support.patch disables the resmgr support
   in SANE which is no longer needed in SANE because resmgr
   works now outside of SANE via ACLs for the scanner
   device nodes.
----------------------------------------------------------------

And our disable-resmgr-support.patch is
(too long lines are shown wrapped here):

Mad world: I added a patch to get rid of those stuff which
was initially introduced by us.


By the way:
Some time ago resmgr was completely replaced by a HAL-based stuff
but now HAL will be dropped (because HAL is declared "deprecated")
so that the HAL-based stuff was already in advance replaced by a
udev-based stuff (of course until this will be replaced by whatever
future "completely-new-and-better-than-anything-else-stuff" ;-)
