We need to find a fix for #2153 and #2155 that still allows reinstallableLibGhc = true.

The problem seems to be that:

  • As of ghc 9.8.1, boot packages built by hadrian have the suffix -inplace.
  • Haskell.nix runs make-install-plan with the ghc-pkg list in scope and the planner finds -inplace versions of the packages and includes them in the plan.
  • Haskell.nix is looking for the -inplace version of the packages, instead of getting them from hackage.

In #2158 we set reinstallableLibGhc = false for ghc 9.8.1. It would be good to avoid this.

One solution might be to tell the planner to choose hackage versions of the packages, but I don't think this will work for the ghc package because it is not in hackage.

@andreabedini is there a way we could deal with the -inplace packages in the plan as if they were did not have the -inplace suffix?
