Root-User : Unset

[TheAnachron]

Hey guys, I've just read this post.
A friend of mine has told me to set a root password and use root (f.e. switching to su in terminal and work with root rights instead).

Is there any way to unset the root password? I know how to use sudo now.

Yep, you can lock the root account password with:

sudo usermod -p '!' root

Is this the exact same thing as after the installation of Ubuntu?
Is there anything I should take care of?

Yes.

Make sure that your user has full sudo rights. It's in the admin group & the sudoers file contains the following line: %admin ALL=(ALL) ALL.

groups

sudo cat /etc/sudoers

The following will remove the root account password altogether, thereby making it like it was originally.

sudo passwd -d root

* NOTE
Nevermind this post. While it disables logging in to root using su, it does allow local terminal access to root without a password so probably NOT what you're looking for.

Nope, that deletes the password. By default the root account password is locked. See:

man passwd

Yeah, I just realized that my suggestion allows LOCAL terminal logins to root without a password so definitely not how it is by default! I'll make a note on my post above.
