Hi. In an effort to shrink our rootfs by some major numbers we found two low-hanging fruits that we would like to address before cherry picking and removing lots of good linux functionality. We have no need for the uImage (3MB) stored in /boot and also we can leave out the terminfo tree (2.5MB). My question here now is if the build system provide functionality to actually tell the image builder not to include these specific components?
From kernel.bbclass, you just need to clear RDEPENDS_kernel-base in your .conf files: # Allow machines to override this dependency if kernel image files are # not wanted in images as standard RDEPENDS_kernel-base ?= "kernel-image" You'll still get your kernel modules installed after making this change.

Or do we need to write some post installer for our rootfs that mounts the image, removes the files, and then umount it? If we remove inclusion of any kernel modules it seems that /boot is never populated? But we need the modules. Also, what package brings in terminfo? Is it as simple as writing a .bbappend to remove it att deploy time?
