External kernel modules are a given kernel specific.  One would
think that should be reflected in a package name, or maybe better
"identifier", or otherwise you have quick descent to madness in a
system maitenance.

Hm, why really hideous?  Any better proposals from a point of
view of a system user?

That indeed could be a serious problem but maybe there are ways to
fix that?  It sounds like you are looking at the issue from the
wrong end; possibly a false impression.

It does not seem to be good enough in this form.  If you happen to
have kernels 2.6.10-%{release} and 2.6.10-%{release+1} installed in
parallel then you need modules for both.  You may also have smp and
non-smp and maybe something more.  Or you mean different releases of
module packages for the same kernel?  Then "2.6.10" is far from
sufficient. You would need a kernel version, kernel release and a
module release somewhere in this logic and quite a bit of change in
a supporting infrastructure if you want to avoid an existing practice
of making a kernel version and a kernel release a part of a module
package name.  The trouble is that various existing tools all over
the place use these 'n-v-r' package identifiers and breaking that
expectation does not sound like a very exciting prospect. Hacking
CVS and bugzilla makes the problem at least limited to more or
less one location.  Some "special" names with a "variable" part
by a convention, for example?  Do I miss something?
