Since when? D-bus is some GUI depoendency. On my console-only servers, it's
not needed, and not installed:

# dpkg-query -s libdbus-1-3 dbus
dpkg-query: package 'libdbus-1-3' is not installed and no information is available
dpkg-query: package 'dbus' is not installed and no information is available
# dpkg-query -l \*dbus\*
dpkg-query: no packages found matching *dbus*

It's also not needed on a basic GUI system. Firefox complains about saving
preferences if it's not running, but runs just fine:

$ pgrep dbus
$ ps 6570 19644 25779 29487 29492
PID TTY STAT TIME COMMAND
6570 ? Sl 1:48 iceweasel

My daily desktop also has
# CONFIG_CGROUPS is not set

And no systemd. Udev actually does something useful, so I have it on my
desktop, but I have machines with a static /dev instead.
