The best approach to separating user privileges is to have one part running as a daemon, under the `root` user, and to send commands from the web part to the other part, for example by creating a file in a special directory or by connecting to a pipe or (domain) socket.	[reply] [d/l]

Do you want to? Sounds a tad dangerous. The problem with su(1) is that it prompts for a password, you might try sudo(1) instead - but it takes a bit of setting up.	[reply]

... and having www-data as a sudoer is dangerous, too. I would go with Corion's option. Rule One: "Do not act incautiously when confronting a little bald wrinkly smiling man."	[reply]
