Description of problem:
SELinux is preventing useradd from 'write' accesses on the sock_file system_bus_socket.

*****  Plugin catchall (100. confidence) suggests   **************************

If aby useradd powinno mieć domyślnie write dostęp do system_bus_socket sock_file.
Then proszę to zgłosić jako błąd.
Można utworzyć lokalny moduł polityki, aby umożliwić ten dostęp.
Do
allow this access for now by executing:
# ausearch -c 'useradd' --raw | audit2allow -M my-useradd
# semodule -X 300 -i my-useradd.pp

Description of problem:
Found this while using a live of Fedora 26 Workstation (2060416 compose), during the installation of the new system on a qemu/kvm guest.

Comment 5 Giulio 'juliuxpigface' 2017-04-27 18:26:59 UTC 
Proposing as a FE for Fedora 26 Final.

The SELinux' denial is caught after the boot of the live environment.

It's not strictly a blocker, since no notifications pop up and so it doesn't violate the "2.5.4 SELinux and crash notifications" Final criterion.

Howewer, in my opinion, it might be a "bad presentation" for the new release, if not fixed in time.
