I think if you read the section on pre-init scripts you can see that the
way dovecot works is something like to keep long term auth processes,
but to fork a new server process for each user. So I guess each login
will instantly see the new binary...
Perhaps you could build a binary package, then in some slightly quiet
time you could install the package and slip a "/etc/init.d/dovecot
restart" on the end? I *think* that the way the restart works is to
keep existing clients alive until they quit (it's an option in the conf
file though?)
I'm out of my depth to be honest, but you didn't get an answer, so
perhaps that helps a little..?
