  there's one other complication -- even when i think i follow the
code, i like to look at sample recipes to confirm my understanding,
but that's when i run across stuff like this in
sysvinit-inittab_2.88dsf.bb:

  pkg_postinst:${PN} () {
  # run this on host and on target
  if [ "${SERIAL_CONSOLES_CHECK}" = "" ]; then
       exit 0
  fi

so i have the docs, the code and the sample recipes all seeming to
disagree with each other.
