Subject: careful review of kdbus

Hello!

In the light of

* kdbus support is no longer compile-time optional. It is now
always built-in. However, it can still be disabled at
runtime using the kdbus=0 kernel command line setting, and
that setting may be changed to default to off, by specifying
--disable-kdbus at build-time. Note though that the kernel
command line setting has no effect if the kdbus.ko kernel
module is not installed, in which case kdbus is (obviously)
also disabled. We encourage all downstream distributions to
begin testing kdbus by adding it to the kernel images in the
development distributions, and leaving kdbus support in
systemd enabled.

I hope you kernel developers will still review kdbus carefully as you did so
far, instead of giving in to any downstream pressure by distros.

It is exactly this attitude and this approach of systemd upstream that I
feel uneasy about. Instead of humbly waiting and working towards having
kdbus accepted to the kernel, systemd developers seem to use any means to
create indirect pressure to have it included eventually.

I hope that it will still be technical excellence as entry barrier for
anything that goes into the kernel.

Please note: I do not judge upon the technical quality of kdbus. I think
others are more knowledgeable to do it.

Thank you,

a patch to remove all of that code would be welcome...
