It looks like what I did in 2.3.8 should still work - control_rancid
puts the diff output into $TMP.diff so add this bit:
grep "^Index: " $TMP.diff | awk '/^Index: configs/{
if ( ! got1 ) { printf("/usr/local/bin/myscript.sh "); got1=3D1; }
printf("%s ", $2)
}
END{ printf("\n") }
' >$TMP.doit
/bin/sh $TMP.doit >$TMP.out
if [ -s $TMP.out ] ; then
.. send mail / whatever
rm $TMP.doit $TMP.out
fi
