   we're bumping into the restrictive upper bound in hnix when trying to move nixpkgs to GHC 9.10 https://hydra.nixos.org/build/306255030/nixlog/1

   This log is for hashing, not for hnix. Reported here: wangbj/hashing#4

   When I fix that and build hnix with GHC 9.10 in the haskell-updates branch, I get this error:

   src/Nix/Effects.hs:40:1: error: [8;;https://errors.haskell.org/messages/GHC-87110GHC-871108;;]
       Could not load module ‘System.Nix.Nar’.
       It is a member of the hidden package ‘hnix-store-nar-0.1.1.0’.
       Perhaps you need to add ‘hnix-store-nar’ to the build-depends in your .cabal file.
       Use -v to see a list of the files searched for.

   Of course, the above error only appears, because we did doJailbreak on the package already. If we don't, we get these bounds errors:

   Encountered missing or private dependencies:
       aeson >=1.4.2 && <1.6 || >=2.0 && <2.2,
       bytestring >=0.10.8 && <0.12,
       containers >=0.5.11.0 && <0.7,
       extra >=1.7 && <1.8,
       filepath >=1.4.2 && <1.5,

       megaparsec >=7.0 && <9.6,
       template-haskell >=2.13 && <2.22
   

   So there is more work to do here, for sure!
