Well, we switched *all* packages from dependencies on installed files
to dependencies on stamp files when migrating them from hand-coded
makefiles to the package infrastructures, so I don't think we should do
the opposite for the Linux kernel package.

But maybe we need to provide for each package (kernel included) a clean
and nice mechanism to delete their stamp files so that they get
reinstalled at the next make invocation.

Regardless of the solution chosen, I think any change in this direction
should come with a clear update in the documentation. I don't want to
see dozens of different hacks^Wmechanisms to do partial rebuilds being
added all over the place without any coherency nor documentation.

Regards!

Thomas
