svn commit: r299523 - head/sys/kern

[Edward Tomasz Napierala]

Author: trasz
Date: Thu May 12 07:38:10 2016
New Revision: 299523
URL: https://svnweb.freebsd.org/changeset/base/299523

Log:
  Stop hiding errors that result in failure to mount /dev.  Otherwise,
  missing /dev directory makes one end up with a completely deaf (init
  without stdout/stderr) system with no hints on the console, unless
  you've booted up with bootverbose.
