installer: simplify the per-build installation
The goal is to allow the installation and testing of arbitrary Nix
versions. Extend the base installer to accept a `--tarball-url-prefix
<url>` to change where the Nix tarball is getting downloaded from.
Once this is merged it should allow to:
1. Pick an evaluation at https://hydra.nixos.org/jobset/nix/master that
looks healthy
2. Select the installedScript build and find the store path.
Now equipped with all of this, use an instance of nar-serve to fetch the
install script and release tarballs:
curl -sfL https://nar-serve.numtide.com/nix/store/rkv4yh7pym941bhj0849zqdkg2546bdv-installer-script/install \
| sh --tarball-url-prefix https://nar-serve.numtide.com/nix/store
Or with cachix, strip the /nix/store and derivation name and then:
curl -sfL https://mycache.cachix.org/serve/rkv4yh7pym941bhj0849zqdkg2546bdv/install \
| sh --tarball-url-prefix https://mycache.cachix.org/serve
Fixes #4047
