When working with a in-tree initrd, the generation of the initrd has the
side effect of placing the initrd in /boot as well (in addition to the
deployment to the deploy dir). This part is currently skipped in case
the initrd is taken from the sstate cache, leading to reproducibility
issues of non-wic images (e.g. a rootfs tarball).

While this is just a reproducibility issue on wic images (as the initrd
is anyways replaced by the one from the deploy dir), it is a bug that
breaks booting on non-wic images.

Best regards,
Felix

  rootfs: make DEPLOYDIR available to all rootfs
  fix(rootfs): generate in-tree initrd as part of image install
