I've dug into this a little deeper (sadly not too much, I don't think I'll have
time to work on this before a while).
Let me summarize the issue: packages can be fetched from two main resources:
- the TeXlive subversion repository (what we are doing now) which bundles
everything into a single massive folder.
- CTAN which distributes everything as separate packages.
The problem with CTAN is that it's not versioned and there is no "stable" URL
for the packages.
To paraphrase
https://github.com/NixOS/nixpkgs/blob/master/pkgs/tools/typesetting/tex/texlive/default.nix:
--8<---------------cut here---------------start------------->8---
# Upstream refuses to distribute stable tarballs,
# so we host snapshots on IPFS or on our own servers.
# Common packages should get served from the binary cache anyway.
# See discussions, e.g. https://github.com/NixOS/nixpkgs/issues/24683
urlPrefixes = args.urlPrefixes or [
# A snapshot temporarily hosted by @xeji.
# TODO: remove when there is a reliable long-term solution
https://cat3.de/texlive-2018/tlnet/archive
# TODO: Add second, faster and more reliable snapshot mirror,
# maybe on one of our project's servers
# IPFS seeded by the mirror above - this may be quite slow
https://ipfs.io/ipfs/QmT4Z67wXin1Z9DhvqwSSkSZSuu8hT6LgDyMu6CBm9Tb7t/tlnet/archive
# The canonical source moves quickly and will be broken almost immediately
http://mirror.ctan.org/tex-archive/systems/texlive/tlnet/archive
# Should be stable for historic, archived releases
# http://ftp.math.utah.edu/pub/tex/historic/systems/texlive/2018/tlnet-final/archive
# TODO: use this later when 2018 is archived
];
--8<---------------cut here---------------end--------------->8---
The core question for us is: "Can we reconstruct a TeXlive package from the
subversion repository?"
Corollary: Was NixOS right to discard the repository as a source for packages?
If we can't reconstruct packages from the subversion repository, then our
current texlive-build-system is not very useful when centered around
texlive-ref.
Nix auto-generates all packages from this file:
http://mirror.ctan.org/tex-archive/systems/texlive/tlnet/tlpkg/texlive.tlpdb.xz.
This could be our redeemer :)
