Agreed. I basically just sent Julian the same message off-list.

I think the current default is fine. Someone who compiles kdbus.ko
probably does that for a reason. The only reason, why we might consider
switching the default to off, is that the Debian kernel suddenly starts
building kdbus.ko and we don't feel comfortable yet, running kdbus by
default for everyone. So far, kdbus has not yet been merged upstream and
I don't know of any plans that the Debian kernel team considers shipping
a distro-specific patch which adds kdbus support.

But let's bring them into the loop here:
@Debian kernel maintainers: Please give us (pkg-systemd) a heads up,
whenever you consider enabling kdbus in the Debian kernel.

Regards,
Michael
