Error during provisioning of gateway

[herzogf]

I tried to provision a physical raspberry pi 1 as gateway - this worked alright but during the restart of the dnsmasq server the whole pi freezed. I had to reboot it (power off/on) and it came back online.
A second run of homek8s without any changes ran just fine.

We have to repeat this test i.e. provision a raspberry pi with brand new raspbian sd card, monitor the memory usage during the homek8s run and analyze the raspi system logs in case the pi freezes again.
