I'm noticing a weird behaviour in firewall-cmd on a fresh openSUSE Tumbleweed
JeOS image. firewall-cmd shows an active docker zone, however docker is not
installed.

> firewall-cmd --get-active-zones
> docker
>   interfaces: docker0
> public
>   interfaces: enp1s0
> localhost:~ # ip l
> 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
>     link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
> 2: enp1s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP mode DEFAULT group default qlen 1000
>     link/ether 52:54:00:73:a3:78 brd ff:ff:ff:ff:ff:ff
> localhost:~ # docker 
> -bash: docker: command not found

Tested on the fresh current openSUSE Tumbleweed JeOS image, out of the box
after the first run wizard. No additional packages are installed, nor did I
touched any other system configuration.
