synopsis: wrap filesystem exceptions more correctly
issues: []
prs: [11378]
---
With the switch to `std::filesystem` in different places, Nix started to throw `std::filesystem::filesystem_error` in many places instead of its own exceptions.
This lead to no longer generating error traces, for example when listing a non-existing directory, and can also lead to crashes inside the Nix REPL.
This version catches these types of exception correctly and wrap them into Nix's own exeception type.
