Like --fork and --nofork, these override what the configuration says.
Use --syslog-only to force the systemd services to log to the Journal
(via syslog, which means we see the severity metadata) instead of
testing sd_booted() in the configuration implementation.

We install the symlink to enable dbus.socket statically, so it doesn't
make much sense to invoke `systemctl enable` on it; and
dbus.service should normally be started by socket activation
(or possibly an explicit dependency) rather than manually.

The socket path used here, $XDG_RUNTIME_DIR/bus, does not match
what was used in user-session-units, but is what Lennart recommended
on fd.o #61303, and is also what kdbus will use for its bus proxy.
Installation of these units switches D-Bus to a different model of
the system: instead of considering each login session (approximately,
each password typed in) to be its own session, the user-session model
is that all concurrent logins by the same user form one large session.
This allows the same bus to be shared by a graphical session, cron jobs,
tty/ssh sessions, screen/tmux sessions and so on.
Because this is a different world-view, it is compile-time optional:
OS builders can choose which world their OS will live in. The default
is still the login-session model used in earlier D-Bus releases,
but might change to the user-session model in future. Explicit
configuration is recommended.
In OSs that support both models (either for sysadmin flexibility or as
a transitional measure), the OS builder should enable the user bus
units, but split them off into a dpkg binary package, RPM subpackage etc.;
the sysadmin can choose whether to enable the user-session model by
choosing whether to install that package.
