Typically you'd make a copy of the serefpolicy-x.y.z directory under the
BUILD directory, modify that copy, generate a diff, and add that to
the .spec file as a further patch on top of the existing ones (not as a
replacement for them). Then use rpmbuild to regenerate the .src.rpm
with your modifications.
A quick google search found this:
But fundamentally it isn't any different than creating a src rpm in the
Ideally you'd upstream your changes to the refpolicy, although you may
need to regenerate your patches relative to it then.
You can wrap your entries with an ifdef(`distro_xxx', `...') and build
with DISTRO=xxx to enable them so that they are only applied for that
