commit 6310dff1dc3d9a6979312f93466d58650c1fe322
Author: Oleg Pykhalov <address@hidden>
Date: Tue Mar 6 15:42:49 2018 +0300
services: dovecot: Copy dovecot.conf to /etc/dovecot.
Many Dovecot utilities compiled with assumption of
‘/etc/dovecot/dovecot.conf’
existence.
* gnu/services/mail.scm (dovecot-shepherd-service): Move config generation.
Invoke ‘dovecot’ without ‘-c’ flag.
(%dovecot-activation): Copy ‘dovecot.conf’ to ‘/etc/dovecot’.
(dovecot-service-type): Make ‘%dovecot-activation’ non-constant.
