# 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:

    $ journalctl -b | grep kdbus

    kernel: kdbus: initialized
    systemd[1]: Inserted module 'kdbus'

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.
