Planning slight re-structure to move "Shutdown, reboot, suspend, exit, launch terminal from SLiM" from "other options". This is to add a greater emphasis on these important commands (i.e. very useful where a mis-configuration results in being unable to progress past the login screen).
Warn against usage?
On the #archlinux IRC Channel, sometimes users come in having problems with Slim. The response/advice is usually to switch to another DM. The channel factoid !slim states: "Don’t use it. It doesn’t play nicely with systemd, in part due to not being aware of sessions. It’s broken and has bugs that upstream refuses to fix."
