[$] Fedora and pkexec

The nasty vulnerability in pkexechas been rippling through the Linux world,leading to lots of security updates to the underlying polkitauthorization toolkit. It also led to a recent discussion on the Fedoradevel mailing list about whether pkexec, which runs aprogram as another user, is actuallyneeded-or wanted-in some or all of the distribution's editions. But pkexecis used by quite a few different Fedora components, particularly indesktop-oriented editions, and it could perhaps be a better choice than thealternatives for running programs with the privileges of another user.
