What we need here is an interface for the initramfs builder to update the boot loader if necessary. No such interface exists yet, AFAIK.
Agreed, this is a different ABI. The wish for such ABI being treated as a cross-package ABI still exist.
One approach would be to create a page at wiki.debian.org which all interested parties could then subscribe to.
I would dislike if (as in the past) we simply rely on whatever internal routines implemented by the most popular packages (initramfs-tools and minux-2.6) which others then need to track sources of.
I suggest something like the following: 1. Boot loaders that maintain block lists install a script under /etc/mkinitramfs/post-update.d which takes two arguments: the kernel ABI version (uname -r) and the absolute path to an initramfs. 2. Initramfs builders call the scripts in this directory after creating, updating or deleting an initramfs by running: run-parts --verbose --exit-on-error --arg=$version --arg=$path /etc/mkinitramfs/post-update.d or similar. We could alternately use multiple directories or an argument to distinguish creation, update and deletion. However, I suspect that these scripts will need to invoke the same command in all cases.
