Hi,
this patch would also help in situations where the kernel needs an
initrd, but it is build completely decoupled from the rootfs. This
includes building UKI images for embedded boards, as well as dm-verity
/ dm-crypt protected rootfs. There, the checksum of the rootfs
container needs to be encoded into the initramfs, hence the initramfs
cannot be generated as part of the rootfs build.

The use-case from above should be considered orthogonal to the inter
package dependencies. If we had conf.d style support for the update-
initramfs.conf, we had a perfect solution for this use-case:
- After debootstrapping, add a config file with update_initramfs=never
to the conf.d folder
- install rootfs, no matter if packages depend on initramfs-tools or
not, the initrd will not be generated
- after rootfs generation, create the initrd either with debian
tooling, dracut or any other mechanism.
Is there a chance that such a patch would be accepted by Debian?
