Yea, I ran dnf under strace to see what directories it poked
around in and that appears to be the only place it looks.
I had hoped to see it looking in some additional place
like /etc/dnf/dnf-plugins, but I didn't notice anything
like that.

Anyway, I appear to have managed to write an "afterdnf"
plugin that starts a background job to wait for the
pid that ran the plugin to go away, then runs some hooks
once dnf has exited. For adapting my "big hammer" to
fedora 22:
