Right now you can compile rust kernel modules and use them, but actual development is still difficult because it does not support rust-analyzer.

Thanks for the great project. Are you aware of the necessary changes to make the VM work on a M1 aarch64 machine?

Kernel 6.1 now supports rust. I will wait to see if nixpkgs decides to package 6.1 with CONFIG_RUST. If so then the primary thing to figure out is compiling rust kernel modules. Otherwise, will also need to figure out compiling the kernel with rust support.

Recieve an error for the module! proc macro on both 6.1 and RFL. Full error is:

proc macro `module` not expanded: Proc-macro dylib loading failed: No such file or directory (OS Error 2)

See if enabling ccache[1] for nix builds speeds up kernel compilation times. Need to look at these workarounds[2]. If it works well can enable the use case of in tree kernel development.

As the flake gets more complex with more options, the flake.nix file is getting cumbersome (already at ~700 lines). Refactor it it into multiple files.

• Refactor into a library of builder functions
• Redo the directory structure
• Expose the library to users
• Update the readme
