An update of time fixed the build. But since t-rex is now replaced by bbox-tile-server, there are no release plans. Is there a deprecation mechanism in NixOS, or should I help with packaging bbox? @sikmir ?

Is there a deprecation mechanism in NixOS

Yes, we can deprecate t-rex in nixpkgs. But it would be great to keep t-rex functional and give users some time to migrate.

should I help with packaging bbox?

bbox draft PR is here , but it fails to build (see NixOS/nixpkgs#335821 (comment))
