Here is the idea developed at Atlas Copco.
Not my code, but I thought it useful for this problem
define three bbclasses.
production.bbclass, rnd.bbclass, release.bbclass containing:
==========================
# Class for use in BBCLASSEXTEND to make it easier to have a single recipe that
# build and generate packages separately for release and normal images.
#
# Usage:
# BBCLASSEXTEND = "release"
CLASSOVERRIDE .= ":class-release"
python release_virtclass_handler () {
# Do nothing if this is inherited, as it's for BBCLASSEXTEND
if "release" not in (d.getVar('BBCLASSEXTEND') or ""):
bb.error("Don't inherit release, use BBCLASSEXTEND")
return
# Restore BPN
bpn = d.getVar('BPN')
newbpn = bpn.replace('-release', '')
d.setVar('BPN', newbpn)
# Use default FILESPATH searching for patches and files
filespath = d.getVar('FILESPATH', True)
newfilespath = filespath.replace('-release', '')
d.setVar('FILESPATH', newfilespath)
}
addhandler release_virtclass_handler
release_virtclass_handler[eventmask] = "bb.event.RecipePreFinalise"
==========================
In a bbappend you use the classes:
==========================
SRC_URI_append_class-production = " \
file://rcS.production \
"
SRC_URI_append_class-rnd = " \
file://rcS.rnd \
"
SRC_URI_append_class-release = " \
file://rcS.release \
"
do_install_append_class-production () {
install -m 755 ${WORKDIR}/rcS.production ${D}${sysconfdir}/init.d/rcS
}
do_install_append_class-rnd () {
install -m 755 ${WORKDIR}/rcS.rnd ${D}${sysconfdir}/init.d/rcS
}
do_install_append_class-release () {
install -m 755 ${WORKDIR}/rcS.release ${D}${sysconfdir}/init.d/rcS
}
BBCLASSEXTEND = "production rnd release"
==========================
In your production image you add
IMAGE_INSTALL_append = "busybox-production"
Do something similar for the other two.

<[email protected]<mailto:[email protected]>>:
I have to say defining multiple distros and then tweaking recipes according to
those definitions is not a good practice, as recipes should generally only
access DISTRO_FEATURES and otherwise be distro-agnostic. The above iptables
scenario should be handled with different image recipes, which pull in (via
packages) or create different configurations.
That has sense. We will refactorize our Yocto repo as suggested. Always very
helpfull with all your comments Mr Alexander. Thank you very much! :)
