I did this because I was trying to make bus-proxyd optional, however
it does not work as stdio-bridge uses that. so yes we can leave the
kdbus part in without worries.

indeed they are not big per se, but see my other email about tmpfiles,
they contribute to a misinterpretation of systemd. since they are
optional I want to make that clear and help the user to choose.

I do have a complete set of packages for yocto that generates that
nicely and the final system size difference is huge: 7.5 to 30Mb
(whole system, not just systemd, but the dependencies, etc -- in
contrast sysvinit + busybox is 6.5Mb).

as I wrote in the other email, I'll make sure that some packages are
highly recommended (ie: journal, udev, sysctl...), but forcing
everyone to ship a ntp client (timesyncd) is asking for trouble when
people analyze systemd x options.

systemd is great and it avoid people doing mistakes where it provides
elegant solutions, but we need to get it in :-)
