New Revision: 281785
URL: https://svnweb.freebsd.org/changeset/base/281785
Log:
Always send log(9) messages to the message buffer.
It is truer to the semantics of logging for messages to *always*
go to the message buffer, where they can eventually be collected
and, in fact, be put into a log file.
This restores the behavior prior to r70239, which seems to have
changed it inadvertently.
