dovecot - Nov 2017 - dovecot initscript

Hi,

about https://wiki.dovecot.org/DovecotInit, i wondered
about
stop)
     if test $running = yes; then
       echo "Stopping Dovecot"
       kill `cat $pidfile`
       echo "."
     else
       echo "Dovecot is already stopped."
     fi
     ;;

Is "doveadm stop" technically the same, or better/worse/safer?
Does "doveadm stop" wait until all child processes are finished,
or would "sleep 1" in the restart-function still be necessary in this
case?

Is "kill -HUP `cat $pidfile`" technically the same as "doveadm
reload"?

If it'a all fine to use doveadm in an initscript, i there a reason to 
not add "doveadm start" to doveadm functionality? Surely this is not 
that important, but maybe a bit more consistent.

Thanks,

Johannes
