Correct approach would be to save state before installation of new
version starts and start dovecot (if flag is set) after old version is
removed - that would mean %postun script. This does not seem to work on
reinstall (the same version is installed) - %postun script is not executed.
Please also consider what happens when the new version of Dovecot requires a
new version of some library. RPM will ensure that both packages are updated in
the same transaction, but if I understand correctly it's not until %posttrans
that you can be sure that the new library is in place.
%postun is sufficient, but it's not executed on package reinstall
one reason more why the cuurent behavior re-starting services
on updates is simply wrong:
You complained that service is restarted during update. Well, in this
case, restart is not sufficient. We even have to be sure, the service is
not running when there are both old and new files in place. Not
restarting the service would be "simply wrong"
