I'm waiting for Nix to stop churning so I can try out the template. I noticed a few things:

1. The instructions on the devos website for getting started don't work because the example nix-shell invocation refers to the master branch, but devos has no master branch and its default branch is main

2. Even though I added nrdxp's cachix instance, I had to build Nix, deploy-rs, and nvfetcher from source, which is taking a long time (mostly just for Nix itself, I think)

In reply to @kraftnix:matrix.org
the need to build nix, deploy-rs and nvfetcher is definitely and issue that we should resolve if possible

its one of the reasons i dont build devos on my laptop anymore

In reply to @ultranix:matrix.org
how is deploy-rs set up to read home-manager.shared-modules

deploy-rs doesn't have to do anything; it's just deploying a NixOS host flake

digga uses fup's hostDefaults.modules to add home-manager to all the host flakes

what does setting

nixConfig.extra-experimental-features = "nix-command flakes ca-references";

at the top of flake.nix actually achieve? won't Nix not actually read the flake anyway, it those features are not enabled?
