[yocto] How do I create a recipe for laying down post-build config files?

Well, now that I've resolved my spelling error, the build succeeds, but my pkg_postinst_${PN} () function doesn't seem to run.
I suppose I'm resigned to making .bbappend recipes to lay down my revised version of the config files.
at least they can all be localized in a layer. Sometimes you just have to bite the bullet and do things
the right way.
However, I don't know how to go about removing files and links after the build is done, and running transformative scripts on other files. For example, see the following code examples that I want to
replicate.
#Remove unneeded services from startup
echo Remove unneeded services from startup
rm ${D}/etc/rc5.d/S20nfsserver
rm ${D}/etc/rc5.d/S20syslog
rm ${D}/etc/rc5.d/S70lighttpd
#Remove /var/log link to /var/volatile/log, persist log.
rm ${D}/var/log
mkdir ${D}/var/log
mv ${D}/etc/default/volatiles/00_core ${D}/etc/default/volatiles/00_core.orig
grep -v volatile/log ${D}/etc/default/volatiles/00_core.orig | tee ${D}/etc/default/volatiles/00_core >/dev/null
rm ${D}/etc/default/volatiles/00_core.orig
Any ideas how to do this?

Subject: How do I create a recipe for laying down post-build config files?
I'm trying to gather all my post-build tweaks into a recipe that will be built as part of an upper-level layer, so that they are installed after the meta layer is processed. Many of these could be accomplished as part of .bbappend files for the recipes that originally supply the config files, but I wanted to gather all my customizations in one spot, so that they're easy to find.
The recipe doesn't actually build anything, so there's no do_build task.
This is surely something that is commonly wanted.
Here's my current recipe, in spectra-postbuild_0.1.bb.
When I try to build an image, the build fails with
ERROR: QA Issue: spectra-postbuild: Files/directories were installed but not shipped
/RELEASE-NOTES.txt
When I disable the installed-vs-shipped QA test, it fails later when it can't find a package file.
I must be missing something critical here?
