Anaconda installer images size on osbuild generated images.

[mmartinv]

Comparing the sizes of the Anaconda installer images on regular Fedora releases vs IOT releases we can observe a huge difference

curl -sL https://kojipkgs.fedoraproject.org/compose/39/latest-Fedora-39/compose/Everything/x86_64/os/images/install.img -o ./fedora-install.img
curl -sL https://kojipkgs.fedoraproject.org/compose/iot/Fedora-IoT-39-20240118.0/compose/IoT/x86_64/os/images/install.img -o ./fedora-iot-install.img
du -sh fedora-i*
545M	fedora-install.img
1,2G	fedora-iot-install.img

Is that difference justified?

The 'Everything' install.img is created using a different process -- Lorax removes a large pile of unneeded files from the root filesystem in order to save space on the boot.iso (which is what that install.img is from). See https://github.com/weldr/lorax/blob/master/share/templates.d/99-generic/runtime-cleanup.tmpl

Thanks for the info and the link!

We are in the process of migrating all the artifacts generation to osbuild but there are some missing pieces like the netboot bits (Please see #394). We are considering the creation of a new image type to provided them and while investigating the missing bits this size difference caught my eye, that's why I opened this issue. It might worth it to discuss whether it makes sense (or not) to provide the missing bits in #394.
