Urks. Now it's all backwards.
A service making use of these macros should never invoke "systemctl"
directly, and especially not "systemctl enable", since that makes the
whole "preset" logic useless. Presets are about moving the enablement
policy out of the packages, so that policy and mechanism are neatly
separated.
For services which should not be restarted on upgrade (D-Bus, ...) we
should recommend this:
%postun
%{systemd_postun}
and for services which should be restarted on upgrade, we should
recommend this:
%postun
%{systemd_postun_with_restart} apache-httpd.service
And nobody should use systemctl enable in the spec snippets
anymore. That should be encoded in the preset policy (see other mail I
just sent).
