I'm wary about working in a root shell, and want to set up a sudoer account to SSH into, so I don't accidentally make a typo that messes up the system. I've heard from various people that the more you do through the webgui, the better. But I know there are some things you need SSH for.
So,
What's the preferred OMV way for creating an admin account that can sudo? Specifically, which groups should the new admin account belong to, so that it can SSH and administer the system like root would?
