Yes.  We need to fix syslogd to be able to start before the network
or even FS are mounted and have the only thing that goes 'bad' be the
data to the missing data sinks (disk, network, etc).  A quick fix to
this would be to have syslog get a HUP after each of these events and
start syslogd just as soon as /usr is mounted.
