Hello,
nix-rebuild command after every rebuild complains about package collisions. Is this normal, what should be done to fix the issue?

Some filenames are provided by multiple packages. If you specify more of the (directly or indirectly) it's unclear which should be chosen into the symlinked tree, so it warns you that it chooses essentially "randomly". Most people get some collisions, I think. Either you care or not.

Thanks.

There's another solution: package priorities.
e.g. use (lowPrio util-linux) instead of plain util-linux

Isn't this something that should be fixed in nixpkgs? It sounds weird that it is ok for multiple packages to provide the same filenames. Shouldn't the solution be one of the following:
- choose which one of the packages provides the file(s) and remove it from the rest
- separate the common file(s) into its own module used by the other packages
- make the packages conflicting so that only one can be installed at a time
Or is there some reason why collisions are allowed?

In some cases they are different implementation of the same program (e.g. busybox symlinks).
It's true that the collisions that happen in default system packages should better get resolved on nixos/nixpkgs level and afterwards we can (again) make those same-priority collisions fatal, like it's in nix-env.
