New Revision: 265018
URL: http://svnweb.freebsd.org/changeset/base/265018

Log:
  Turn off the full witness trace on console output.
  
  On head/, or more specifically, when WITNESS is in
  the kernel config, the console is spammed excessively
  with lock order reversal between isofs and devfs.
  
  Set debug.witness.trace=0 in the installer sysctl.conf
  to avoid printing the full KDB stack backtrace.  This
  does not prevent printing the lock order reversal has
  happened, only lessens the console spam.
