[launchd-dev] Starting launch agents

Hi! We have a product that uses launch agents. We'd like to avoid the reboot after install, so we'd like start the agents for *all* the Aqua session-s from the installer. Is it something supported/possible? I tried to implement it by iterating through the '/tmp/launchd-*/sock' files and setting LAUNCHD_SOCKET to these files, then invoking the launchctl command. But it doesn't seems to do it. Any ideas? Regards, Miklos
