I found something that is messed up with flakes:

1. Write src = ./.;
2. On another line write something like something = finalAttrs.src
3. Run nom build

It shows that finalAttrs.src does not match the $src that is unpacked for some reason.

The log outputs will say something like

unpacking source archive /nix/store/6vpcbgxb1lv4xb36i4z0wcns26qkqb0a-ss7yf0ysfsr45a1811bcyvpkblpnhk1q-source
source root is ss7yf0ysfsr45a1811bcyvpkblpnhk1q-source

Notice that this looks like a store path made from a store path. It seems to be, as both store paths exist. But if you write something like:

echo "${finalAttrs.src}"

you will get:

ss7yf0ysfsr45a1811bcyvpkblpnhk1q-source

Since I rely on finalAttrs.src == $src I get a derivation failure. This can be fixed if I write something like src = self; from the flake outputs.

3. Run nom build
