sudo allows privilege escalation for non root users to perform restricted actions while in a locked down user environment.
Emerge
root # emerge sudo
Configuration
Passwordless
The sudo configuration file is located @ /etc/sudoers.
user $ su -c 'nano /etc/sudoers'
Remove the # in the line....
%wheel ALL=(ALL) NOPASSWD: ALL
Add your user to the wheel group to enable sudo:
user $ su -c 'gpasswd -a $USER wheel'
Either log out, and in again or restart:
user $ su -c 'shutdown -r now'
Disabling Root Access By Password
To better secure a system, one may desire to disable root logins by password.
root # passwd --lock root
to access root:
user $ sudo su
Root can also be accessed by logging in via ssh keys, or as a restricted user then sudo su as above.
Bash Completion
Users that want bash completion with sudo need to run this once.
user $ echo "complete -cf sudo" >> $HOME/.bashrc
