We heavily discourage the use of setuid tools, and we're actively trying to cleanse the system of them. Just so I understand what you're advocating here... Are you seriously suggesting that the entire daemon should be privileged rather than using a privilege-separated helper tool? That seems to run counter to generally accepted security practices (make privileged things as small as possible), so I must be mis-parsing your recommendations here... He mentioned that his daemon's plist lives in /Library/ LaunchDaemons and that it was a privileged operation to talk to it, and I mistakenly interpreted that as "My daemon is running as root", which is not necessarily true. So no, I'm not advocating that all system-wide daemons run as root; I mistakenly concluded that his was. I have another question, tho, Damien. If I want to use a UNIX socket to do the IPC, do I have to create the socket myself? launchd doesn't seem to create and bind it when I use the SockPathName key... launchctl will create the socket for you when you load your job. It will give a file descriptor for that socket to launchd, and launchd will give that descriptor to your job when you check in via the launch (3) API. smime.p7s
