    dmesg - Add -f option for continuous monitoring
    * Add the -f option to dmesg.  After the initial message buffer dump
      dmesg monitors the kernel for additional data and displays it as it
      arrives.  dmesg will not terminate until killed in this mode.
    * The sysctl() is deficient so libkvm is forced when this option is
