[Solved] User groups and sudo

logos88 · 2013-04-02 14:05:06

Hello. I have read that with systemd it's not more necesary to put the user in the diferent groups (sys, disk, lp, network, video, audio, optical, storage, scanner, power, etc.).

But, if I don't add the user to wheel, how do I have to configure sudo? Is there any problem adding the user to wheel?

You can add yourself to wheel.
It's also possible to edit yhe sudoers to allow your username, just the same way root is allowed.

Look at: Wiki article about sudo
/etc/sudoers (it is all explained in the file).
man sudoers

In the past, it was recommended to edit the sudoers file only through visudo, because it performs a syntax check, but you should not worry too much, as long as you have a root account.

EDIT: Never mind. I got it the wrong way. You asked about systemd and the wheel group. Sudo only works with groups and users, so if you have to use sudo, then it is safe to do so by adding your user to the wheel account. It does not bother systemd.

I still edit it with

# visudo

Yeah, same here. It's worth noting that you can change the editor visudo uses (see the man page) - though this is not especially relevant to the original question.

Just a general point, it is worth at least a skim of the sudoers and sudo man pages, and the sudoers comments.

Oh, I hate that section. It never works for me! I always read it and then I remove myself from all of those groups and then everything stops working correctly.

Finally I included the user only in the groups wheel and systemd-journal.

In the Users and Groups page (https://wiki.archlinux.org/index.php/Users_and_Groups) says that wheel will be used in the future by systemd to allow starting/stopping services as non-root, and that systemd-journal provides access to the complete systemd logs. Otherwise, only user generated messages are displayed.

Then I made a visudo and uncomented:
#%wheel ALL=(ALL) ALL

Now sudo works good, and I don't have any problems with audio or media devices despite not being in any other groups.

I'm glad you got it worked out. Please add [Solved] to your thread title.

All the best,
