Portfile munin @1.4.7:
---
startupitem.create  yes
startupitem.name    munin-node
startupitem.start   "${prefix}/sbin/munin-node"
startupitem.stop    "kill `cat ${prefix}/var/run/munin/munin-node.pid`"
---

/opt/local/sbin/munin-node is a perl program. I see see no reason for daemondo here. launchd KeepAlive would only keep daemondo alive, not the executed munin-node.

The second daemon munin-asyncd is new functionality for munin 2.0 and is also only executing a perl program.
