  Hi,
 
  I am using the current kernel for qtexended on FR available from
  mwester.  I also downloaded the minimal kernel module set from
  http://moko.mwester.net/dl.html#kernels.
 
  The version of the module set and the kernel seems to be matching, but
  after extracting the modules on my system, I now have two directories
  under /lib/modules (as I had expected): 2.6.24 (the original kernel) and
  2.6.24mw-g291a9d50 (the minimal module set).

 A given kernel is going to look for its modules down only one path.  We
 have been using these build-specific paths in the git build system for
 some time, they eliminate the problem that incorrect modules get loaded
 into kernel space when you change the main kernel binary.  I dunno what
 our packaging side is doing about modules because it's not discussed
 anywhere that I read.

 Anyway it's good news mwester is using the same system, it just means
 that you only actually need the dir that matches the build stamp of the
 monolithic kernel you are using; any other dirs left lying around don't
 make any trouble except waste space if you will never revert to the
 kernel that matches them.

 Update:

After deleting the 2.6.24mw-g291a9d50 branch from under /lib/modules and
rebooting, I found that the original kernel looks for modules under it (the
deleted branch).  So it is useful, after all.

I don't know what additional utility it provides, though.
