Puppet runs as root during startup, from [http://hg.mozilla.org/build/puppet/file/tip/modules/puppet/files/puppet-atboot.plist /Library/LaunchDaemons/com.mozilla.puppet.plist]. This runs [http://hg.mozilla.org/build/puppet/file/tip/modules/puppet/templates/puppet-darwin-run-puppet.sh.erb run-puppet.sh], which runs puppet repeatedly until it succeeds, rebooting after too many failures. When this script is finished, it touches /var/tmp/puppet.finished, which signals the buildslave startup launchd script to start. | |||
[http://hg.mozilla.org/build/puppet/file/tip/modules/buildslave/templates/org.mozilla.build.buildslave.plist.erb That script] is a LaunchAgent, which means it will run as any logged-in user. Using ''users::builder::autologin'', the builder user is logged in. The script is configured to run when /var/tmp/puppet.finished is changed. It merely invokes runslave.py. | |||

The /Library/LaunchDaemons/com.reductivelabs.puppet.plist runs /usr/local/bin/sleep-and-run-puppet.sh as root, which is presumably installed as part of the base image. This script sleeps for 60 seconds, then runs puppet in the foreground every 60 seconds until it succeeds. | The /Library/LaunchDaemons/com.reductivelabs.puppet.plist runs /usr/local/bin/sleep-and-run-puppet.sh as root, which is presumably installed as part of the base image.
