Looks okay to me.  Probably the easiest thing to do is to put it in
redhat-rpm-config for now[1] and then go from there.  If anyone
disagrees with it, raise your hands... otherwise, I'll get it in the
start of next week


[1] Basically, we'll change the macros to call a brp-python-post in
redhat-rpm-config.  That script will call the one in stock rpm as well
as do the hardlink steps.
