# Using Puppet with launchd

Apple Computer has made it clear that the future of application and

4

1

server launching is their new launchd. Whether or not you have an

5

1

affinity for launchd, it appears to be here to stay, replacing SysV

6

1

Init as well as the newer StartupItems. The configuration of each

7

1

server is done with (surprise) XML property lists.

If you would like to run puppetd with launchd, you'll need to put

1

the folowing content into

1

/Library/LaunchDaemons/com.reductivelabs.puppet.plist:

Now use the launchctl program to make launchd aware of the new

88

1

services (the -w makes launchd permanently aware of the new

89

1

daemon):

90

1

91

1

    % launchctl load -w /Library/LaunchDaemons/com.reductivelabs.puppet.plist

92

1

    % launchctl load -w /Library/LaunchDaemons/com.reductivelabs.puppetmaster.plist

93

1

94

1

As with all

95

1

[launchd plist files](http://developer.apple.com/technotes/tn2005/tn2083.html#SECSECURITY),

96

1

owner and group of the file wants to be root:wheel, and permissions

97

1

want to be 644 (owner has read/write, group and other read-only)

98

1

The services should now launch at boot-time.
