tracker looks in its directory tree for executable files to make available as subcommands. Users expect to find subcommands from tracker-miners package but that fails as they are in different tree. We also cannot change the lookup path since tracker-miners also depends on a library from tracker package. Until we can break the dependency cycle on package level: tracker -> tracker-miners -> tracker-sparql (tracker) we need to work around it. I chose to set an environment variable that overrides the subcommands lookup to a tree symlinking files from both packages in GNOME NixOS module. https://gitlab.gnome.org/GNOME/tracker/-/issues/341 Fixes: https://github.com/NixOS/nixpkgs/issues/153378
