Hi all,

I have created an installer for my daemon application. I want my daemon to run as root after installation. Before installation I used to run daemon using "sudo launchctl load /Library/LaunchDaemons/ com.mycompany.mydaemon.plist". In installer I tried using run command or run script but it works only in 10.4.11 ppc but not with 10.5.4 intel. I want to set some file permissions/ownerships also but it doesnt work. Installer can be run only from admin users. Is there anyway to run daemon as root using command or script?

This is not a limitation of the installer. This is a limitation of the sh (and perl). Well, not really a limitation, it's a security feature. Some script interpreters will refuse to run a script as root as a security precaution. I don't recall the exact details about when this choice is made or how to overcome it.

My choice for overcoming the problem was to choose a different interpreter (python). I suppose it's just a matter of time before that door is closed also.

I'd like to know what the alternatives are so that scripts within an installer can be run with Administrator/root privileges.

Just in case, a simple solution is probably to: 1) Be sure that the installer requires an admon/root authentication. 2) Use sudo to call launchctl even from the shell script. ------------------------------ Message: 2 Date: Mon, 6 Apr 2009 12:25:51 +0530 From: Rakesh Singhal <rakesh.singhal@gmail.com> Subject: Re: Run daemon from installer as root To: duanemurphy@mac.com, darwin-dev@lists.apple.com Message-ID: <bbf18850904052355q42fa27aauace063307cbe036d@mail.gmail.com> Content-Type: text/plain; charset="iso-8859-1" Hi Duane, I am using InstallAnyWhere to create installer. I am trying using excuting commands or script but I am not able to do it. But I think, I will have to use "sudo launchctl load /Library/LaunchDaemons/com.mycompany.mydaemon.plist" to load my daemon and run it. Is it possible that when installer execute this command or script, it can pop-up for authentication? Please advice me.
