- Breaks VirtualBox DHCP when using Network Manger (in Kicksecure) after VM reboot (
sudo reboot). It is functional for the first start after powering off and powering on the VM. [1]

Could be a Network Manager issue:

[1] Before someone says that's a VirtualBox issue, no, I mean, maybe, but that doesn't matter.
VirtualBox is a valid environment. If that breaks, other environments will break as well.
Broken networking is extremely frustrating. MAC randomization would be suitable for Kicksecure, but only if stable.
It's not important enough to break common network configurations in common environments.
TODO: This bug has to be reported to Network Manager (NM) as above bug reports apparently never have reached upstream NM.
