Let me put it in concrete terms.

Is it possible to write a bb recipe in a way like this?

---------------------->snip<-------------------------
...
IF IMAGE USES UPSTART AS INIT THEN

inherit autotools

do_install_append() {
    install -d ${D}${sysconfdir}/init
    install -m 0644 ${S}/upstartscript ${D}${sysconfdir}/init/foo.conf
}

ELSE

inherit autotools update-rc.d

do_install_append() {
    install -d ${D}${sysconfdir}/init.d
    install -m 0755 ${WORKDIR}/initscript ${D}${sysconfdir}/init.d/foo
}

INITSCRIPT_NAME = "foo"

FI
