Problem with CentOS package for 2.3.0 and old dependency in systemd with clean install

[TG Servers]

Hi,

you definitely have a problem with the packages out of your own repo for
version 2.3.0 and CentOS.
And this is only if you do a clean install, meaning there was no lower
dovecot version ever running on the system.

If you want to 'systemctl start dovecot' it breaks with a dependency
error which comes from dovecot-init.service.

dovecot-init.service :
[Unit]
Description=One-time Dovecot init service
ConditionPathExists=|!/var/lib/dovecot/ssl-parameters.dat
ConditionPathExists=|!/etc/pki/dovecot/certs/dovecot.pem

[Service]
Type=oneshot
RemainAfterExit=no
ExecStart=/bin/sh -c '\
if [ ! -f /etc/pki/dovecot/certs/dovecot.pem ]; \
then\
  SSLDIR=/etc/pki/dovecot/
OPENSSLCONFIG=/etc/pki/dovecot/dovecot-openssl.cnf
/usr/libexec/dovecot/mkcert.sh /dev/null 2>&1;\
fi;\
if [ ! -f /var/lib/dovecot/ssl-parameters.dat ]; \
then\
  /usr/libexec/dovecot/ssl-params >/dev/null 2>&1; \
fi'

It wants to call /usr/libexec/dovecot/ssl-params if
/var/lib/dovecot/ssl-parameters.dat (which is deprecated now as I
understood) is not existing.
The problem is in 2.3.0 /usr/libexec/dovecot/ssl-params is not existent
anymore.

This error does not occur if you for instance install 2.2.x from the
base repo, start it once, and then update the version from your repo.
This is because the ssl-parameters.dat was created with the old version
then.

But this should not be the expected behaviour I think. It should be
possible to do a fresh install of 2.3.0 on a fresh system.

Can you please get back to me on that?

Thanks,
Thomas
