[yocto] How to force bitbake to install a package

[Matt Schuckmann]

Ok I'm trying to really dig into this to understand it and I've discovered that for my current problem the pkg_postinst_${PN}() is not getting run. I fact what I keep seeing is the remnants of an older version of pkg_postinst_${PN}() function. 

I have yet to figure out how to debug or see the execution of pkg_postinst functions, they seem to be different from the do_install(), do_compile() functions but I'm having trouble finding documentation on them.

Here is my current pkg_postinst function
pkg_postinst () {
	touch $D${sysconfdir}/foo.bar.conf
	if [ -f $D${sysconfdir}/lighttpd.conf ] ; then
		cat $D${sysconfdir}/lighttpd.conf.web-api >> $D${sysconfdir}/lighttpd.conf
else
	echo "No lighttpd.conf found, aborting"
	exit 1
fi
}

Any suggestions as to why this isn't getting run? 

Thanks, 
Matt S.
