kdbus

kdbus is an alternative in-kernel implementation of D-Bus.

Installation

Install the kdbusAUR package, then add kdbus=1 to the kernel parameters.

After rebooting, you can verify a working kdbus installation with:

$ dmesg | grep kdbus
kernel: kdbus: initialized

Also check that /sys/fs/kdbus/ contains the 0-system/ folder, denoting the system bus. Another sign of a working kdbus installation is that, after invoking busctl, the DESCRIPTION column should not be entirely empty for all services.
