I noticed that when installing xorg using ports there is an option to configure with or without setuid. At first glance, I would think that if given the option, I should choose to have it unset, because it sounds safer. By doing this though I'm unsure what functionality I'd be losing. I had a look at 11.14 of the FAQ, which cleared a few things up. I'm still wondering why setuid is the default. I'm planning to use a login manager, so if I keep setuid off, will I be losing (or gaining) anything?
