then we'd be doing this at the package level, which we're trying to
avoid. And this plugin is useful beyond this situation.

I think the plan would look something like:
- drop this plugin into the yum pkg, enabled by default, for fc6
- drop this plugin intpo the yum pkg, enabled by default, for rawhide/f7

- mark that hal.i386 should be removed from x86_64 boxes if found (ditto
hal.ppc64 on ppc64 boxes)
- mark out any others we want to nuke as it goes.

that's it.

and speaking of that - I realized the file format needs to be slightly
more complex in order for it to be the same file used across archs.

It should probably look like:

pkgname/glob: arch-it-is-on

or:

<removespec pkgmatch="some-pkg-v-r.arch" on_arch="i386">


that way we can make sure that on i386 boxes we don't remove hal.i386.
b/c there it is actually desired. :)

Thoughts?
