[Working] Remove su-related TODO

The reality of the situation is kind of complicated.
Canonical su(1) is based on PAM, and PAM can require whatever it wants.
The default however, does not require a special group.
Further, alpine uses busybox by default, which also has no such
requirements.

 Sometimes, you'll want to do something that *does* require administrative powers.
 While you may switch to a different tty and log in as root, this is often inconvenient.
 You may gain root privileges ad-hoc using either the built-in busybox utility `su`, or the common external utility `sudo`, available in the package named the same way.
-// TODO: verify that `su` truly does not require any special group.
 `sudo`, unlike `su`, will require additional configuration.
 The `visudo` utility that comes with it allows you to safely edit the `sudoers` file which configures it.
 The difference between `sudo` and `su` comes down to which side the permissions come from - `su` allows you to temporarily log-in as another user (and thus requires that you enter the password of the user you wish to log in as), while `sudo` allows you to perform commands (including login shells) as the target user, assuming the configuration gives you that right (meaning that your password is the one used for authentication).
