This made me think of the trick we use to force a kernel rebuild with
this newly-created initramfs.

We're using a post-fs target to force the kerbnel rebuild:
    ROOTFS_INITRAMFS_POST_TARGETS += linux-rebuild-with-initramfs

But this rule is not PHONY, and your series does not make it PHONY.
This could be done in a fallow-up patch, and is not a blocker.

Regards,
Yann E. MORIN.
