I have been building a NixOS package for FreeFileSync Business Edition for its capabilities of silent installation. However, there are several problems.
- The file names contain [] but nix interpretes those as array marker or something. I agree, that nix should be able handle that correctly, however, on the command line this characters in file names are tiresome escape needies.
- The installer looks for /bin/bash. This is not quite portable. Why does it not rely on the path?
- I set symlink on a bash to that path but still the installer fails miserably with "Could not find path to terminal executable" quite immediately.
Are there any plans to support systems like NixOS?
Kind regards
