Which groups are still necessary?

Hello guys,

from the beginning of my arch usage I'd put myself into the groups the beginners guide recommended. But which of them are today still useful and which of them simply unneeded?

Here's my list of groups I'm in:

[orschiro@thinkpad ~]$ groups
network video audio optical storage users abs

To concretise my question: would my network still work when I'm not in network or would my intel graphic setup with kms display everything correctly when I'm not in video? Would I have sound without audio group? [...]

Best regards

Re: Which groups are still necessary?

So by default the primary group is users when you don't specify it elsewise?

Re: Which groups are still necessary?

Why have a group named after your name? Confusing.

Hmm...  never really thought about it.   It is the default bahaviour in Fedora/Ret Hat.

users

Does anyone actually find the users group useful?  Especially if everyone is a member....    Giving everyone permission for something can be handled with standard file permssions.

Re: Which groups are still necessary?

users, wheel, audio

"audio" seems to be necessary, seeing as I'm the only one using this computer "users" and "wheel" are probably redundant.

Re: Which groups are still necessary?

Wheel group was essential in my gnome install to use gksu.

I thought that too but I kicked myself out of it for testing purposes, rebooted machine and alsa is still working fine here.

So generally spoken most groups are completely unneeded today?

Re: Which groups are still necessary?

I know about the wiki article but obviously even the groups that were listed there as useful are not necessary.

Hence my discussion on this issue.

Re: Which groups are still necessary?

so here is my 2cents.

because we know have polkit & consolekit, when a user is authenticated using that, it has the right privileges and groups are not needed. how can you use that?
1) by using a graphical login manager that can do that automatically. only gdm and kdm can
2) in .xinitrc, use "exec ck-launch-session wm"


Give what you have. To someone, it may be better than you dare to think.

Re: Which groups are still necessary?

Having a group named the same as your user is default in ubuntu aswell.  You tend to find this out with nfs shares when you have a server/client ubuntu/arch mix smile

Anyway for the record

wheel games audio optical storage users vboxusers usbmux
