I'd like to suggest that this should only be done for daemons where there
is anything that a sysadmin can sensibly configure in this way. The patch
proposed for #712167 (native Upstart init support in dbus) did this, but
after checking the available command-line options in dbus-daemon, I couldn't
actually find any command-line options that can be changed by a sysadmin
without breaking system integration; so I think it's OK that the systemd
unit doesn't read /etc/default/dbus, and I don't think the (potential future)
Upstart job should either.
If dbus-daemon had command-line options that made sense as local configuration,
then reading /etc/default/dbus would be fine, but I've tried to avoid that
in favour of having anything locally-configurable only be available in the
(XML) configuration files, and not on the command-line: see
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=712167#20 for more on
command-line options vs. configuration.
(Perhaps this means /etc/init.d/dbus should stop reading /etc/default/dbus...)
