I'm running FreeBSD 11 with gnome3 on top of x.org. i`m interesting in creating a situation of boot-up straight to chromium running as root user.
one of my very first issues is creating the auto-login condition. how can this be done?
Answer the questions as you see fit but be sure to add the new user in wheel group when asked which other groups it should be invited to;
# pkg install security/sudo;
Find and uncomment the # %wheel ALL=(ALL) ALL line, save and exit;
# reboot now;
Login using the user you just created;
Perform any tasks you need high privileges for using sudo;
Install a Display Manager and configure it to autologin as the user you've just created (look here for more info about this);
Forget about login as root unless you have a very good reason to do so. Stick to the Principle of Least Privilege and work around your needs with su and sudo;
P.S.: I only use DM in Ubuntu and have no idea if a thing such as autologin - even as a regular user - exists in the first place. Most likely (some of) it does but you'll have to Google for I can't help you with this.
