Regarding garbage collection - redling list
- https://ianthehenry.com/posts/how-to-learn-nix/saving-your-shell/ - the hands-on part that is very enlightening starts basically with the
$ ln -s /nix/store/4n40rm31n58ga0xl62nanq13a34axwwx-nix-shell.drv /nix/var/nix/gcroots/per-user/ian/nix-shell-teststatements - https://www.reddit.com/r/NixOS/comments/1as7dp3/protect_flake_shell_used_with_nix_develop_from/ (https://www.reddit.com/r/NixOS/comments/1as7dp3/comment/kqoukxp/) -
nix-add-root-devshellfunction explains the case of flakes here - https://github.com/nix-community/nix-direnv/tree/master?tab=readme-ov-file#flakes-support - often suggested
- NixOS/nix#3995 (comment) - talks about inputs that might still be gc'd and provides a workaround in form of a
collectFlakeInputsfunction, even links to - https://github.com/ruuda/dotfiles/blob/1a28049980c61f22706b2d5d3e8f8951527403a3/zsh/.zshrc#L142-L158 - a shell function that uses
nix flake archiveto persist inputs as well, testedln -sapproach for now only, seems insufficient as when I change text in resume.typ there, typst-packages >500M get redownloaded again on next build - https://medium.com/@ejpcmac/about-using-nix-in-my-development-workflow-12422a1f2f4c - it seems we either need
keep-outputs = true keep-derivations = trueor the nix-store--gc arguments--option keep-derivations true --option keep-outputs truestill to keep our roots from being collected
