Security updates.  If you're required to upgrade D-BUS because of an
exploit.  Once the system bus is restarted, NM will die.  Bad thing:
system looses network connection.

You can still argue that post-install of RPMs simply should not restart
the service but this will leave your system vulnerable until you reboot.

Am I missing something?  HAL, for example, has a similar approach.
