FYI nix unstable is broken right now, avoid updating

Just tested with flk core to rule out it being my config:

❯ flk NixOS build
warning: Git tree '/home/cody/try-flake-core-2021-05-23/flk' is dirty

People are working on it, this is the related issue: NixOS/nixpkgs#124215

Workaround (untested):

nix.sandboxPaths = [ "/bin/sh" ];

source: NixOS/nixpkgs#124215 (comment)

Workaround isn't working placing that nix setting here, but this is probably the wrong place:

❯ git diff lib/devos/mkHosts.nix
diff --git a/lib/devos/mkHosts.nix b/lib/devos/mkHosts.nix
index 8e2a799..ee2abb2 100644

I got around it by doing the other fix suggested in that thread:

❯ git diff lib/devos/mkHosts.nix
diff --git a/lib/devos/mkHosts.nix b/lib/devos/mkHosts.nix
index 8e2a799..5ffa4f9 100644

+      documentation.info.enable = lib.mkForce false;

Then sandboxPaths was fixed and I could switch to the newest nix unstable that fixes this issue (I think, we'll see).

Thanks for your report and links to upstream!

At this moment, is there anything left for us to track here?

Nope, things are all good for me now and I assume the windows for others to encounter this is closed now.
