If these files are overwriting files owned by some other packages, then
you will loose that customization when the package is upgraded by
package manager (unless those files are listed in CONFFILES). You need
to use RREPLACES at least.

? do_install installs them to $D not root fs which doesn't even exist yet.

You might also need to skip strip if there are also some binaries which are
already stripped, skip ldflash qa check if they don't have matching hash
type etc
