But am I seriously mistaken, or is it again some info about how
to run postfix supervised?  And not about how to grab postfix
log messages so as to be able to use "svlogd"?

The fact that several people seem to imply that it isn't trivial
(such as the need for a patch to be applied, as stated above) to
run postfix under runit make me wonder about the example script
provided by Gerrit Pape, copied here below:

---CUT---
#!/bin/sh
exec 1>&2

daemon_directory=/usr/lib/postfix \
command_directory=/usr/sbin \
config_directory=/etc/postfix \
queue_directory=/var/spool/postfix \
mail_owner=postfix \
setgid_group=postdrop \
  /etc/postfix/postfix-script check || exit 1

exec /usr/lib/postfix/master
---CUT---

[No mention of any caveat.]
So actually, is this sufficient or not to run postfix under
supervision???


Thanks for your advice,
Gilles
