lib/common.sh has passwordless sudo check #1288
Description
The passwordless sudo check in lib/common.sh is really idiotic. It requires you to have passwordless sudo in the first place, and secondly it needs to be configured the exact way that it then checks.
Instead, the script should just check that it is running as root, and should not run anything with sudo. Then it is up to user to run the top-level command with sudo, which allows it to have password or configure the passwordless in any way user wants.
In general, any lib should not execute code, but only define functions for scripts to execute.
