The above is definitely not what you want.  It will keep debug symbols in all of
your binaries, increasing the size of the eventual image.

The base-files recipe created a set of directories.  If this directory is empty
on your resulting image, I would assume it is created from there.  If this is a
concern, create a bbappend and remove that directory in a do_install_append.

Is there any particular reason you want it removed?  It should only be taking 1
inode, assuming it is empty.

My image recipe pulls the packagegroup-core-boot, ROOTFS_PKGMANAGE_BOOTSTRAP, CORE_IMAGE_EXTRA_INSTALL, ca-certificates, package-management and some other private package but none of those include -dbg...
