Sounds reasonable. I'm not familiar enough with the RPM internals to
understand when each hook is called, and that key steps are happening
between... is this explained anywhere - short if reading the src?

I'll probably do this. Thanks for the hint...

I cannot :-/ Part of the problem is that this is a package that was
clobbering other packages' conffiles in %post . Evil spawn.

The new-and-improved version I have is much saner, but still ends up
clobbering a couple of conffiles. As you can imagine - it's not for
inclusion in Fedora proper.

(Wherever possible it uses conf.d type facilities. And several of the
files being clobbered are the /etc/sysconfig/<service> files to point
the daemon to an alternative config file. Still, somewhat ugly.)

Wow! Now that's an interesting tidbit. Hmmm, Lua...
