Why does anything other than a kernel update require a reboot?
The system bus cannot be restarted. Similarly, any apps you have
running will be using old libraries so things like glibc you really want
to reboot for.
The problem is mainly one of state. For example, NetworkManager has
some code to handle reconnection to the system bus. But to
transparently handle bus restarts, NetworkManager would have to perform
the following actions; none of this is NM or D-Bus specific, it would be
the same problem in any system using separate services for specific
functions, as is the unix way.
*snip*
We've discussed less-invasive ways of fixing this, like queuing signals
in the services on the service-side in libdbus or so until the service
reconnects to the system bus, but that could be quite tricky and error
prone. You cannot do a 75% solution here.

Of course all this is SEP when dbus becomes a kernel module :)
