The aarch64 musl bootstrap tools are woefully outdated. Just getting
them to the point of being able to build new versions of themselves
required a number of hacks[1] that can be reverted once we have new
bootstrap tools, and before that it stdenv didn't even build for the
preceding three years.
[1]: https://github.com/NixOS/nixpkgs/pull/169764
So, following the script established by previous bootstrap tools
updates:
Files came from this Hydra build:
https://hydra.nixos.org/build/246470544
…which used nixpkgs revision dd5621df6d
to instantiate:
/nix/store/g480ass2vjmakaq03z7k2j95xnxh206a-stdenv-bootstrap-tools.drv
…and then built:
/nix/store/95lm0y33dayag4542s8bi83s31bw68dr-stdenv-bootstrap-tools
I downloaded these files from Hydra and prefetched them into the Nix
store with the following commands:
STOREPATH=95lm0y33dayag4542s8bi83s31bw68dr-stdenv-bootstrap-tools
OPTIONS="--option binary-caches https://cache.nixos.org --option trusted-public-keys cache.nixos.org-1:6NCHdD59X431o0gWypbMrAURkbJ16ZPMQFGspcDShjY="
nix --extra-experimental-features nix-command store prefetch-file \
file://$(nix --extra-experimental-features nix-command store add-file --name bootstrap-tools.tar.xz $(nix-store ${OPTIONS} -r /nix/store/${STOREPATH})/on-server/bootstrap-tools.tar.xz)
nix --extra-experimental-features nix-command store prefetch-file --executable \
file://$(nix --extra-experimental-features nix-command store add-path --name busybox $(nix-store ${OPTIONS} -r /nix/store/${STOREPATH})/on-server/busybox)
These commands produced the following output:

I used the hashes from the output above to create the fetchurl
invocation which is part of this commit.
I then started the bootstrap with the following command:
nix --extra-experimental-features nix-command build -L -f . --arg localSystem '(import ./lib).systems.examples.aarch64-multiplatform-musl' hello
As @lovesegfault requested, here are the the sha256sums of all the
on-server components for extra verification:
sha256sum /nix/store/${STOREPATH}/on-server/*
…which produced the following output:
