------------------------------------------
BTW, I would like to be the assignee of this issue, but I can't. (There is no
"Assign to me" Button)
How can I assign issues to myself ?

> In firewall.py, {{"systemctl is-active iptables || systemctl is-active
> firewalld"}} is passed to {{run_in_shell}} function, which splits cmd string
> by using {{shlex.split}}.
> {{run_in_shell}} function finally calls {{subprocess.Popen}} with
> {{shell=True}}, so the cmd string is evaluated like {{Popen(['/bin/sh', '-c',
> 'systemctl', 'is-active', 'iptables', '||', 'systemctl', 'is-active',
> 'firewalld'])}}. This doesn't returns values as expected, because after
> args[1] (in this case, after the first {{is-active}}) are evaluated as sh
> arguements.
> {{systemctl is-active}} can take multiple arugments, so we can use it.
