[Debian-salsa-ci] Replacing Kaniko with something that among others can create a riscv64 image

[Otto Kekäläinen]

Hi Santiago!

I see you are implementing
https://salsa.debian.org/salsa-ci-team/pipeline/-/issues/331 in
https://salsa.debian.org/salsa-ci-team/pipeline/-/merge_requests/521
and https://salsa.debian.org/salsa-ci-team/pipeline/-/merge_requests/523.

Can you elaborate a bit in #331 what are your design principles, for
example why you chose Kaniko? Why not use regular "podman build"? Do
you plan to rename all Dockerfiles to Containerfile, or rewrite them
to bash scripts that issue "buildah run" commands?

Can you also write something about what is your test plan or rollout
plan, and perhaps how confident you are in the design, and is there
some parts of it Ahmed could help with?

Ahmed had set time aside for this task, so if you share a bit more
about your plans, I think Ahmed can align and assist you so you
together achieve this migration faster and with higher confidence.
