obsoleting -selinux subpackages

[Wart]

In an earlier F-? release, I had added a cyphesis-selinux subpackage
which added selinux protection to the cyphesis game server.  This policy
has now been added to the selinux-policy-targeted package, and I need to
have cyphesis-selinux removed.  There are two places where this can be
done safely, afaik:

(a)  Add 'Obsoletes: cyphesis-selinux' to the cyphesis base package
(b)  Add 'Obsoletes: cyphesis-selinux' to the selinux-policy-targeted
package

I'm tempted to go with (a) because it keeps us from having to add many
Obsoletes: tags to the selinux policy packages as the -selinux
subpackage get merged in.

Is (a) an acceptable solution?
