something else that grates on me:

$ grep "grep.*/dev/null" *
autotools.bbclass:              if grep "^[[:space:]]*AM_GLIB_GNU_GETTEXT" 
$CONFIGURE_AC >/dev/null; then
autotools.bbclass:                      if grep "sed.*POTFILES" $CONFIGURE_AC 
>/dev/null; then
autotools.bbclass:              elif grep "^[[:space:]]*AM_GNU_GETTEXT" 
$CONFIGURE_AC >/dev/null; then
autotools.bbclass:              if grep "^[[:space:]]*[AI][CT]_PROG_INTLTOOL" 
$CONFIGURE_AC >/dev/null; then
insane.bbclass:            statement = "grep -e '%s/[^ :]\{1,\}/[^ :]\{1,\}' %s 
> /dev/null" % (exec_prefix, path)
insane.bbclass:        statement = "grep -e 'CROSS COMPILE Badness:' -e 'is 
unsafe for cross-compilation' %s > /dev/null" % compilelog
insane.bbclass:        statement = "grep -e 'CROSS COMPILE Badness:' -e 'is 
unsafe for cross-compilation' %s > /dev/null" % installlog
insane.bbclass:                gnu = "grep \"^[[:space:]]*AM_GNU_GETTEXT\" %s 
>/dev/null" % config
rootfs-postcommands.bbclass:            if grep -q DROPBEAR_EXTRA_ARGS 
${IMAGE_ROOTFS}${sysconfdir}/default/dropbear 2>/dev/null ; then
utils.bbclass:  if echo "$destpath/" | egrep '^${STAGING_LIBDIR}/' >/dev/null
$

  1) can most of those be simplified with "grep -q"?
  2) is there any need for "egrep" in that last match?
