Use deb packages as binary sources

[layus]

I wonder if there is a way to use deb packages hosted on https://apt.llvm.org/ as binary source. While binary packages are provided by volunteers hand there is uneven support for systems, the apt repo contains releases for each llvm version and several ubuntu versions.

Has someone ever tried that ? How hard would it be to redirect toolchains_llvm to a local repository_rule containting the unpacked and merged packages ?
