Quick answer: Don't build multiple distros in one build directory.
You might get away with setting TMPDIR = "tmp-${DISTRO}" to give each
its own.
But I'd rather advice to set up two separate builds and just point the
downloads and sstate-cache to the same location. It'll be faster than
the TMPDIR option.
Or figure out how to put the difference in the IMAGE only. Then you can
just build both images (in parallel, woot), which is faster, more
convenient and saves on diskspace.
What I often do is have my-application.bb generate a
my-application-utils package that only gets installed in the "dev" image
but not in the production one, which only installs "my-application".
You could also create a "my-application-dev.bb" recipe that includes
my-application.bb and just changes what it needs to be different.

Hi all,
I'm currently using an additional layer and image to differentiate
between a release and development build (enabling NFS, SSH, root login,
etc.). To create a development build, I manually add the layer to
bblayers.conf. This works quite well, but feels a bit clumsy to
integrate into a CI/CD pipeline.
Per these past discussions here [1][2], I'm now trying to migrate to
multiple DISTROs, something like "mydistro" and "mydistro-dev".
While migrating some of the changes, I discovered that I run into
caching(?) issues. I have a recipe for an internal application and want
to include additional systemd service files in the development image.
What I did was this:
Added "application-dbg.service" to recipes-internal/application/files
Adapted application.bb recipe:
SRC_URI:append:mydistro-dev = " file://application-dbg.service"
do_install {
# ...snip...
# systemd service
install -d ${D}${systemd_system_unitdir}
install -m 0644 ${WORKDIR}/application.service
${D}${systemd_system_unitdir}
}
do_install:append:mydistro-dev() {
# debug systemd services
install -d ${D}${systemd_system_unitdir}
install -m 0644 ${WORKDIR}/application-dbg.service
${D}${systemd_system_unitdir}
}
When I run "DISTRO=mydistro-dev bitbake application" followed by
"DISTRO=mydistro bitbake application", the debug service file is still
present in the package. This seems to be caused by the "image"
directory in the recipe WORKDIR not being cleaned between subsequent
do_install runs. Is this expected behaviour? What's the best solution?
Kind regards,
Nicolas
