The BEAM is fascinating for many reasons, including being register-based.
I really just wish the BEAM was portable in the way the JVM is. The BEAM hooks into so many system libraries, you must compile it on every flavor of linux instead of just unpacking a tarball.
This means you either must use your distro package manager's version, or compile from scratch. If you want to control the exact version that's being used across your team (via `asdf` or similar), this practically means you'll end up compiling the BEAM over and over...
Burrito works very well in my experience. I've used it for distributing an implementation of breakout in Elixir with OpenGL and Metal rendering backends as a binary. Pretty neat!

Inferno is both register based and highly portable using the same tool chain as Plan 9 which runs seamlessly across multiple architectures. This eventually evolved into the Go tooling as Rob Pike came up with the Plan 9 design and worked on it with Ken Thompson. https://seh.dev/go-legacy/
Unfortunately Inferno was never fully completed and bit-rotted a bit but it still builds on systems with 32 bit support. There are various forks and even an attempted 64 bit version. To me its a great design as it not only runs on bare metal but also has a hosted option so it runs under Plan 9, Windows, MacOS/Unix/BSD/Linux. Talk about a portable OS...
To be clear, Inferno is the operating system. The virtual machine is Dis. There exist a few examples[1] of 64-bit Dis, but usually the problem people run into is making the Limbo[2] compiler spit out 64-bit code.
It's rather unfortunate, Inferno is a really nice system with a lot of interesting reference stuff implemented like a typed shell[3]. It's also Plan 9 in a box with all the accoutrements, and knowers will have jumped out of their seat at the implication. I can't understate how cool the Inferno system is.
I dunno what happened to the 64bit port, the author just up and deleted it with no reason given AFIK. Thankfully someone had a recent clone and uploaded it to the archive.
Limbo is incomplete, forget what exactly but a few people on the 9fans discord recently ran into issues. Always remember, Inferno was forced onto the Labs people by Lucent in an attempt to compete with Sun's Java and built in a year. Bell Labs did not do marketing and Lucent fumbled the whole thing.
Plan 9 in a box is only useful if you MUST use a foreign host like Linux. Otherwise I would much prefer the machine actually run Plan 9.
Correct me if I'm wrong, but you'd still have to compile it from source on nix, no?
On my relatively powerful workstation, Erlang/BEAM takes about 7 minutes to compile.
We're working around this currently by having a fat devcontainer image, pre-built with Erlang inside (from source) by our CI. It chews through CI minutes unavoidably due to how docker layer caching works.
It would be awesome to just download and unpack a tarball, regardless of which distro you're using.
Nix is centered around the local Nix store and binary caching.
As long as the specific version of Erlang you’re using is present in either your Nix store or the global cache for your OS and arch (at cache.nixos.org), you should not need to compile anything.
And if you rely on custom builds, you can just setup your own binary cache. This is similar to remote caching in Bazel.
We do exactly this at my dayjob - we have (multiple) very specific combinations of (erlang, elixir, hex, rebar3) that we use which are pinned to exactly the versions we need. We have a private Nix cache so we only have to build them once.
That said, learning nix and setting up a nix cache is still a lot of work. Docker buildx might offer you some more knobs to cache portions of your build in a finer-grained manner without having to take the nix plunge.
Nix is enormously complicated, kind of unstable and not well documented.
I get that if you've gone through the pain of learning it you get a system with some very nice properties. But casually suggesting "maybe try nix" is a bit like telling someone who wants to listen to Mozart "maybe try playing a piano".
OP is already trying to do something pretty un-casual:

So I think it is perfectly appropriate to suggest a sharp tool.
