One thing I'd like us to look into:

My CI failure against master says:

Configuring ghc-lib-parser-ex-8.8.5.8...
Setup: Encountered missing dependencies:
ghc-lib-parser -any

builder for '/nix/store/4bhjr2nz9i2lyffp6ivqwxf7dxakx4ch-ghc-lib-parser-ex-8.8.5.8.drv' failed with exit code 1

And indeed, hackage-packages.nix doesn't list in "ghc-lib-parser-ex" a dependency on ghc-lib-parser, even though the cabal file of that version lists the dependency.

@nh2 It looks like that dependency is behind a flag, which is maybe why cabal2nix isn't picking it up.

@cdepillabout Thanks! And it looks like the logic is changing again: shayne-fletcher/ghc-lib-parser-ex#42

I've asked in shayne-fletcher/ghc-lib-parser-ex#42 (comment).

krank author here. I'm really happy that you are trying krank to track outdated overrides. Please, let me know (here or in krank issue tracker) if there is any improvement I can do.

@guibou I hadn't known about krank until now, that sounds really useful also for my own projects (and especially ugprades of NixOS!).

No specific requests yet, but I noticed one thing: Given that krank is a Haskell program, could you add it to Stackage? That would significantly increase the chances that it itself will not break in nixpkgs (reducing maintenance effort over here), and will also make it much easier to get it to build e.g. in static-haskell-nix.

haskellPackages.ghcWithPackages: fix for GHC 8.10
abc4f96 
This closes #79441.

ghcWithPackages is using `ghc-pkg recache` to build its package
database. By doing so, it overrides the `package.cache[.lock]` files.

Details are unclear, but GHC 8.10 changed a bit the behavior.
Previously, it was unconditionally replacing the files by new ones. Now
it tries to open (for modification) the files. These files are symlinks
to another nix derivation, which is hence read-only.

This commit removes the files before running `ghc-pkg recache`, hence it
will just write the new files.

Tested with `haskellPackages.ghcWithPackages` (i.e. GHC 8.8) and
`haskell.packages.ghc8101.ghcWithPackages` (i.e GHC 8.10) with the
following nix file, at the root of the nixpkgs repository:

```
with import ./. {
  overlays = [
    (
      self: super: {
        haskellPackages = super.haskell.packages.ghc8101.override {
          overrides = selfh: superh: {
             th-lift-instances = super.haskell.lib.doJailbreak superh.th-lift-instances;
             th-expand-syns    = super.haskell.lib.doJailbreak superh.th-expand-syns;
             th-reify-many     = super.haskell.lib.doJailbreak superh.th-reify-many;
             th-orphans        = super.haskell.lib.doJailbreak superh.th-orphans;
             haskell-src-meta  = super.haskell.lib.doJailbreak superh.haskell-src-meta;
          };
        };
      }
  )
  ];
};
haskellPackages.ghcWithPackages(p:[p.PyF])
```

This will test with GHC 8.10. Comment out the `overlays` to test with
GHC 8.8.
