Only if somebody can come up with a check, that really wicked is broken and not
your network cable, your dhcp server or something else in your network.
Else MicroOS would do a rollback, which of course does not help in this
situation, and finally stops the machine.
So instead that wicked can bring the network online e.g., after you plugged in
the network cable, the machine will not come up again anymore.
That's also not what we want.
Not every "fail" of a service can be fixed with a rollback and/or reboot.
