This seems to bite a lot of people (myself included).
Change
IMAGE_INSTALL += “canlogger”
to
IMAGE_INSTALL_append = “ canlogger”
or possibly better
EXTRA_IMAGE_INSTALL_append = “ canlogger”

+= is evaluated immediately during parsing just like = and therefore behaves just like = if the variable did not yet exist.  This then defeats the ?= assignment of IMAGE_INSTALL in your distro/.conf, image recipe, or core-image.bbclass.

The “override syntax” _append gets appended POST parsing and so does not preempt the ?= default assignment.

Subject: [yocto] recipe removing (some)contents of /etc

Hello

I have the below's simple recipe(starting a script in sysV runlevel 2), but when I add it to the image with
IMAGE_INSTALL += "canlogger"
in my local.conf, most of the contents of /etc gets removed/overwritten making the system unbootable.

Does someone sees something wrong?
