This package contains Linux dom0 files, which aren't exactly part of "Qubes
core" i.e. aren't required for normal Qubes usage.

Mostly there are config files for different system services, but also some
"addons" to Qubes core:
 - udev scripts for block and USB devices exposure (in qvm-block and qvm-usb)
 - appmenu generation for Linux GUI (including icons)
