infinite recursion error related to whether a git repo exists #408

[jackmac92]

Is the project currrently in a state where the quick start should be working (would understand if #400 is an issue)

I've been trying to use this project to create my first nixos config, but have been running into some issues with the bespoke iso installer.

If this is not a known issue, happy to add a more detailed bug report, (the issue may be/ likely is me, but I figure this project aims to be friendly to the uninitated, maybe just needs clearer docs)

[nrdxp]

Yeah we definitely want this project to be as easy to bootstrap for new Nixers as possible. As far as I know the quickstart should be accurate, but it has been a while since I started from scratch so perhaps something has changed. Just give us a few more details about the specific issue, and we'll see if we can track it down.

awesome! going to add some notes here as a go

first minor thing, on initial install, should the user do anything in the nix-shell before exiting?

Before #409 you would need to exit the nix-shell in order to initialize the repo/ create the first commit, but now maybe these can just be removed?

---

For building the ISO, I think adding some context to the docs here could be really helpful. E.g. I think that "bootstrapIso" is a specific "type" of bud build, but not sure

bud build bootstrap bootstrapIso
sudo -E $(which bud) burn

Also some docs/context on how/when to use bud vm would be great. It looks like that is an easy way to test things out without the hassle of a full install (will follow up with the issues I've had in bud vm, but this is the area where I think it's most likely I'm just not using it correctly)

Rerunning my attempt to install again so I can get the stacktraces

[jackmac92]

I think my main issue is an infinite recursion error in /iso/devos/, so I run nixos-instal --flake .#NixOS, but not bud up

(too much) detail on how I get to the above error

main attempts to install have been in virt-manager. I only make one change to the repo before starting, to add serial console support for easier access to the vm.

boot.kernelParams = [  "console=tty1" "console=ttyS0,115200"  ];

I follow the quickstart to generate the bespoke iso image. And then use that image the same way I've used an official nixos iso to install nix in a vm.

I get through the install stage bootstrapping, but direnv fails to load the .envrc and nix-shell gets an infinite recursion error. So I'm not able to run bud up as the next steps instruct. I try rebooting since nixos-install appears to succeed. However the vm fails to boot, as it can't find the disk labelled nixos.

I think I usually run nixos-generate-config to install in a VM, that seems like the most likely fix for the disk missing on reboot. But figure the broken nix-shell is probably a bigger problem at the moment

[jackmac92]

looking through other issues I see a lot of my issue is a duplicate of #372

but the above infinite recursion does seem to be a bug not related to the documentation. I also noticed it appears to be the exact same error I had in #408

but previously the error occured on the initial call to nix-shell, before building an iso, now it occurs within the booted bespoke iso

according to @Pacman99

... I think this is caused by devos not being a git repository. I think bud get needs to be updated to just do git clone https://github.com/divnix/devos

so I tried to create a git repo, but can't because it is a ready only file system

[Pacman99]

I think I know whats wrong, the offending line is here:

digga/src/mkFlake/options.nix

Line 258 in fca1df3

default = config.self.inputs.${name};

I think it can just be fixed with self.inputs.${name}.
