The major/minor device numbers may not be portable across OSes, which may be a problem for Nix, so that code may need to be #ifdef’d. > If in future, a package requires access to certain device while > building (or during tests) we can include it in our list of created > device nodes. Yes, but keep in mind that we’re not going to change that often, because it’s inconvenient. Thanks, Ludo’.
