This is not equivalent to what it used to be:
  DOVECOT_CONF=/etc/dovecot/dovecot.${DOVECOT_INSTANCE}.conf
or
  DOVECOT_CONF=/etc/dovecot/dovecot.conf

I wonder if this is acceptable.

Otherwise it looks good to me. But should probably also be flattened to
the dovecot upgrade commit.

Thanks.

old init-script cuts a part of init name after last dot and think it's a
dovecot instance suffix.
if I rename my init script to something like '/etc/init.d/happy.new.fear',
it's would set DOVECOT_CONF to /etc/dovecot/dovecot.fear.conf
I think it's have no sence. I just correct an init script to find the
correct config file.
1. if we have declared non-empty DOVECOT_CONF in /etc/conf.d/${SVCNAME}, we
use it as a config file name.
2. if haven't - we use ${SVCNAME} as a name of config file.

so if the init script name is 'dovecot', the config file name would be
'/etc/dovecot/dovecot.conf' (if DOVECOT_CONF is not set)
and if the script name is 'jack.daniels' the config file name would be
'/etc/dovecot/jack.daniels.conf' not '/etc/dovecot/dovecot.daniels.conf'
