Comment # 8 on bug 1075878 from Johannes P�hlmann

I had "Apocalyptic loss of proc/tmpfs/sysfs mounts" also on openSUSE 15.1. By
stopping open VPN or by pulling a usb network adapter. in fact every taking
down of a network adapter.

I found a possible trigger: I had managed somehow to have network 
manager AND wickedd active. After disabling the network manager packages and 
switching to wicked in Yast, the Problem has vanished. 

I am fine now. The remaining root questions  are: 

* Why was i able to activate network manager AND wicked (Reasons on Level 1-7
;-)
* Why can the combination of network manager and wickedd do such damage ? 
* Should the kernel not defend itself better against such misconfiguration ?
