Do not create the kairos user by default

Tested kairos with this, doesnt seem like an issue. You cannot login but thats about it lol.

If you create a normal user you can still login but without sudo privs unless you add the admin group to your user

$ sudo -i
[sudo] password for itxaka: 
itxaka is not in the sudoers file.
$ cat /et	pas^C

permissions of the user seems good

itxaka@localhost:~$ k3s kubectl get nodes
error: error loading config file "/etc/rancher/k3s/k3s.yaml": open /etc/rancher/k3s/k3s.yaml: permission denied
itxaka@localhost:~$ cat /oem/90_custom.yaml
cat: /oem/90_custom.yaml: Permission denied

So I dont see why this would not work, nothing depends on our kairos user being there by default.

maybe still worth keeping for livecd? though I don't see why someone would log out of the livecd

[Itxaka]

I think you can't log out of the livecd lol, it restarts the service on exit so you get logged in back

Let me try that

[Itxaka]

nope, I think this only happens in alpine, which makes the service restart but not on normal service. You dont even get a login back, just a dead tty lol
