New Revision: 225122
URL: http://svn.freebsd.org/changeset/base/225122

Log:
  Add kern.cam.boot_delay description (with reasonable default) to
  default/loader.conf
  
  This should help people installing ${OS} to USB devices, where there are
  frequently cases where kernel tries to mount root before actual umass sensing
  is finished.
