This is a script that tarballs a numtide/devshell and all of its dependencies, and adds a script that drops users into this devshell with the closure mounted in its expected location.
This script compresses a devshell's entire
closure, symlinks and all, to be
extracted with tar -I zst -xPf ./out.tar.zst -C ./out.
An included script, ./out/start, drops the caller into the devshell inside a
bubblewrap environment where the
closure is mounted at /nix, making it fully usable, even without Nix itself
installed.
In most cases, you should be using nix-portable.
We encountered an exotic environment where systemd was not available
and we needed to share a massive installation of OpenLane 2 across many users.
From what we could tell, nix-portable requires the archive to be stored and
for each user to have a writable space for the archive. This allows the closure
to be shared by multiple users without the Nix daemon (or indeed a Nix
installation at all) available.
