Subject: bitbake of core-image-minimal is sending my fw_env.config file to PC filesystem instead of my squashfs for target

Hi,

I should have done this from the start and started a new topic so please
forgive me if you've already seen this on "No u-boot-fslc-fw-utils recipe
for Dunfell?" thread.

I added libubootenv to my image because I'm using RAUC for updates etc..

Anyway, I'm building a read-only rootfs with squashfs (already working from
my NOR flash) but needed to update that image with libubootenv and needed a
fw_env.config file in /etc.

So first attempt was to make a libubootenv_0.3.1.bbappend like:

FILESEXTRAPATHS_prepend := "${THISDIR}/${PN}/:"

SRC_URI_append += " file://fw_env.config"

do_install_append() {
       install -d ${D}${sysconfdir}
       install -m 0644 ${WORKDIR}/fw_env.config
${D}${sysconfdir}/fw_env.config
}

FILES_${PN} += "${sysconfdir}/fw_env.config"

When I would bitbake core-image-minimal, it updated my squashfs file but
looking at the resulting tar of the rootfs showed it didn't contain
/etc/fw_env.config.  Turns out it's in the directory by itself under
tmp/deploy/images/imx8mmevk!

I checked out the examples in meta-freescale-3rdparty/recipes-bsp that some
of the toradex boards are using and did some other reading online and can't
quite figure out what I'm doing wrong and how to get fw_env.config into my
squashfs image.

I'm using Dunfell with this effort and core-image-minimal to keep size down
since this is a small NOR I'm working on.

Listing so you can see what I'm talking about:
