How can I add my files to a Ezurio Linux build?

Answer

To add files to a Laird Linux build, enable "BR2_ROOTFS_OVERLAY" in your config and provide it with an absolute path to the directory you would like to overlay.  Files in this directory will be inserted relative to "/".  For example, if you would like to add files to "/etc" and the path to the overlay directory is "/buildroot/overlay", create a directory "/buildroot/overlay/etc/<files>".
