A cheesy way to accomplish this goal would be leverage the launchd conditional keep alive logic and the fact that /var/run is guaranteed to be cleaned at boot. This would involve breaking each daemon out into a separate launchd job that is conditionally kept alive whenever / var/run/my-script-is-done exists. The script on the other hand, is also a launchd job, and is kept alive as long as /var/run/my-script-is- done does NOT exist. This script MUST "touch" /var/run/my-script-is- done to signal launchd to stop relaunching the script and begin relaunching the daemons. I hope this is the right list for these questions, if not, please tell me where I should go. I'm working on integrating a set of Linux programs into our product on the mac, and, as in any porting job, I'm having certain problems getting everything to work just right. In this case, the Linux application is actually a set of programs, each of which does a different job, in a particular order. The first program must be run exactly once, before the other programs are run. It creates a set of files that the other programs parse and use while they are running. These other programs are effectively daemons (which have a -nofork option, so they will work with launchd), and need to be kept alive. This means that I can't just write one script that launches them in order, because then the parameters I pass to launchd will either keep the whole script alive, or run it just once. So, what is the best way of forcing the scripts to run in the particular order I want them to run in? This email sent to zarzycki@apple.com This email sent to site_archiver@lists.apple.com
