>Description:
	syslogd has a very nice feature: You can tell it to use a file other
	than /dev/log for its AF_UNIX socket. This is useful if, for example,
	you want that socket to be acessible inside a chroot environment.

	But if you do this, you also want non-chroot things to be able to
	talk to it. The natural way to do this is make /dev/log a symlink
	to the real socket location.

	The problem is that /etc/rc always executes "rm -f /dev/log". This
	loses badly- the symlink is killed and everything expecting the log
	device in the normal place is out of luck.

	There's also a less important problem- the real log device file
	doesn't get removed before syslogd starts, when you boot.

>How-To-Repeat:
	Boot the machine...
>Fix:
	Simple. Add the following line anywhere in /etc/rc.conf:

		real_dev_log=""		# specify path if not /dev/log

	And change /etc/rc (unidiff):
