How can a package I didn't ask for get included in my image?

How can a package I didn't ask for get included in my image?

[Gary Thomas]

Note: I'm not sure the best list to use for this, but I'll start
here.  I build using poky plus my own distro.conf and my own image
recipes, etc.  My example below uses stylized package and target
names.

I'm trying to figure out why a particular package is ending up
in my final image.  If I build something like this:
   % bitbake my-image
If I then look, I find packages that were installed that I'm
never mentioning:
   % grep firmware tmp/work/my-board/my-image/temp/log.do_rootfs
   Installing linux-firmware-wl12xx (0.0+git1+09c949f6d3196a7199eb2c7015bfa5d34ed723b5-r0) to root...
so I tried to figure out how this is getting in
   % bitbake my-image -g
   % grep firmware *.dot
   ... comes up empty

To be fair, I had originally built this image with this in <my-board>.conf
   MACHINE_EXTRA_RRECOMMENDS = " kernel-modules linux-firmware-wl12xx "
but that has since been removed.  Somehow, it's ghost lingers on...

How can this be?
How can I get rid of it, short of a complete rebuild?

Thanks for any insight into this mystery.

Found it myself - the variable MACHINE_EXTRA_RRECOMMENDS was referenced
by my core task, something like this:
   RRECOMMENDS_task-my-distro-boot = "\
     ${MACHINE_EXTRA_RRECOMMENDS} \
   "
I hadn't rebuilt that task, so the reference remained.  I'm still not
sure why it didn't end up in the .dot graphs though.

The dot graphs produced by bitbake -g will include what's projected by the 
recipes, not already built packages; thus why after your change it no longer 
appeared in the graphs. The answer is not to effectively make changes to the 
tasks without bumping the task recipe's PR (or alternatively enable 
BasicHash).

FYI you can enable buildhistory (without enabling BUILDHISTORY_COMMIT if you 
don't need that) and this will produce some dependency graphs directly from 
the packages used to construct the rootfs. These graphs are more focused and 
thus can be a bit more useful when you're trying to figure out how a package 
got into your image; however producing them is part of do_rootfs so you have 
to go through the entire process of building the image in order to get them.

Cheers,
Paul

How do you enable buildhistory?
Thanks

add
INHERIT += "buildhistory"
to your local.conf

Indeed. FYI there is a small amount of documentation on buildhistory here:

https://wiki.yoctoproject.org/wiki/Buildhistory
