[PATCH v3 0/3] Fix data-race in deployment of initrd

[Felix Moessbauer <felix.moessbauer@siemens.com>]

Changes since v2:

- fix check for default initrd

Changes since v1:

- add API changelog entry
- fix expression in INITRD_DEPLOY_FILE
- do not append ${PN} to deploy-dir in image.bb

This patch fixes a data race in the deployment of the initrd, as discussed on
the ML in "Issues creating images with custom initramfs". As a measure against
further races on these files, we also use the sstate cache for deployment.

Please note, that imaging with wic + grub or systemd-boot with a custom
initramfs is still broken. This is due to the wic logic, which reads the
initrd in the rootfs, but not the one in the deploy dir.

Best regards,
