NM depend on messagebus at least, so we should stop NM right before
messagebus.  But the same issues with startup are theoretically present
with shutdown, meaning that since messagebus depends on rsyslog, and
rsyslog depends on network.  Standard installs don't use networked
syslog, so standard installs don't actually need rsyslog to depend on
network, but because rsyslog isn't smart enough to know when it does or
does not depend on network, we can't just re-order the chain... :(
