Why do I sometimes need to authenticate and sometimes not?
Asked by

What always bothered me was that sometimes I need to authenticate for performing some actions and sometimes not. I'll give you two examples:
1. If I reboot using the GUI, I don't get prompted for my password, if I type 'reboot' in the terminal, I get a message that tells me only sudo can do that. So I have to type in my password.
2. If I plug in a USB stick, it automatically gets mounted, if I want to mount a partition using the command line or Truecrypt, I get prompted for my sudo password.
I always got the response that rebooting, shutting down, mounting etc. were root actions only sudo could perform but this raises the question: How can I perform them without typing in my password (which obviously is the case in both examples)?
