Thank you, I will abandon that line of inquiry.

So I now have recipes that attempt to overwrite inittab with their own
custom version.  These individual recipes are included in different
images and have DEPENDS += " sysvinit-inittab" in them.  However, the
resulting image still has the original inittab from sysvinit-inittab
recipe, not the custom inittab in my new recipes.

My recipes look like this now:

LICENSE = "BSD"
LIC_FILES_CHKSUM = "file://LICENSE;md5=9bea9267288f79f074b2e000d3cf6412"
SRC_URI = "file://LICENSE file://inittab-imageX"
S = "${WORKDIR}"
DEPENDS += " sysvinit-inittab"

FILES_${PN} = "/etc/inittab"

do_install () {
    install -d ${D}${sysconfdir}
    install -m 0644 -D ${S}/inittab-imageX ${D}${sysconfdir}/inittab
}

Is there something more I'm missing?  Thanks.
