>Description:
If syslogd is run with -l flag to create additional log sockets it can
under certain circumstances fail to unlink those log sockets before
syslogd is started again.  Syslogd will then report

	syslogd: cannot create /usr/jail/log: Address already in use

>How-To-Repeat:
If the server is power cycled (improper shutdown) syslogd will not get
a signal to be killed and therefore not unlink() the additional log sockets.
I have also seen this behavior during a 'sync;reboot' but I'm having 
trouble recreating that scenario.
>Fix:
Suggest that syslogd on startup automatically unlink() all sockets 
specified with -l as it currently does with /var/run/log, or a new
flag to force the unlinking.
