Yeah, that's not going to work. `exec ejabberctl start' will try to
supervise the
control program which returns immediately and will then fire stop. I guess you
could do something like:
#!/bin/sh
ejabberctl start
exec horrible_listener_script.sh
Where `horrible_listener_script.sh' is something super dirty like:
`while : ; do nc localhost 4369 ; sleep 1; done'
That doesn't fix your logging problem though.

For logging, you could make erlang.log and/or ejabberd.log a fifo, then use a
multilog-style logger service like so:
/etc/sv/ejabberlogger/run
#!/bin/sh
exec < /var/log/jabber/ejabberd.log
exec chpst ejabberd svlogd /var/log/jabber
Which will take logs from the fifo that ejabberd is happily writing to, and
write them back as svlogd managed log files. Again, kinda dirty but
should do the trick.

Are you stuck with the erlang jabber server? It seems like a lot of the issues
are related to erlang daemons being weird. That said, I don't have much
experience with erlang beyond fighting rabbitmq at work so there's probably
a better way within the erlang space that I don't know about.
Cheers!
