New Revision: 225260
URL: http://svn.freebsd.org/changeset/base/225260

Log:
  MFC r225122:
  
   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.
