[launchd-dev] Install and load a launch daemon without a reboot

[Jeremy Reichman]

I'm resurrecting an old thread -- but it was my thread, and I have a
slightly new spin on it.

Is it appropriate to start a LaunchAgent for the current user (with
LimitLoadToSessionType: Aqua) via a script (such as post{install,upgrade})
in an installer? I don't remember this being covered in TN2083, and my
quick re-review of the tech note didn't turn anything up.

If so, is there an acceptable method or process to load the agent?

I am able to load a LaunchDaemon via an installer script, and have done so
via the recommendation of checking to make sure EUID and RUID are 0. My
Python code from earlier in the thread.

import posix
if posix.getuid() and posix.geteuid() == 0:
     # launchctl here

At the very least, I'd expect you'd need to find the current user and load
the agent in that account's context even though the installer and its
scripts are running with EUID/RUID 0.


Thanks!
