Description Petr Šabata 2017-04-24 11:04:40 UTC 
Description of problem:
With DNF2 it's no longer possible to install coreutils-single as it's obsoleted by the main package, "to give priority" to it, according to a comment in the SPEC file.

The reason this ever worked is, according to Igor, a bug in the old DNF which the new release fixed.  That makes sense to me.

Which variant is installed shouldn't be decided by the packager but by the deployment tools, e.g. Anaconda or mock configuration.

Please, revert c553cab787c2499ffaa36748a2de7c0e08fe31d5.

Version-Release number of selected component (if applicable):
8.24-105 and newer.

How reproducible:
Always.

Steps to Reproduce:
1. Attempt to install coreutils-single with DNF2.

Actual results:
coreutils is installed.

Expected results:
coreutils-single is installed.
Comment 1 Petr Šabata 2017-04-24 11:08:38 UTC 
That said, I'm aware coreutils-single provides coreutils (and it should probably provide all the /bin/* tools as well) and I'm not sure which one the depsolver would choose if you simply install "coreutils".  I don't have an advice here; I just know the current implementation is wrong :)
Comment 2 Kamil Dudka 2017-04-25 11:54:42 UTC 
Confirmed.  I can reproduce the issue with dnf-2.3.0-1.fc27.  Even though Igor calls it a bug fix, it is at least a backward incompatible change to dnf, which should be avoided.

I am not against dropping the Obsoletes tag from coreutils but please consider also the compatibility aspect of the dnf change that is causing it.  I am pretty sure that coreutils is not the only package affected by the change (and not all affected packages are under our control).
Comment 3 Stephen Gallagher 2017-04-25 12:14:36 UTC 
Kamil: What if we were to rename the other coreutils package to `coreutils-standard` and have them both `Provides: coreutils` (for compatibility with things that `Require: coreutils` and then we can add `Suggests: coreutils-standard` to the fedora-release package, which will trigger DNF to prefer coreutils-standard if neither of them is currently on the system, but otherwise leave it alone.

coreutils-8.27-3.fc26 has been submitted as an update to Fedora 26. https://bodhi.fedoraproject.org/updates/FEDORA-2017-db1b943779

(In reply to Stephen Gallagher from comment #3)

> `coreutils-standard` [...]

Sounds like a bad idea to me.  We should not rename such fundamental packages to work around limitations of the package manager.

Both the packages provide "coreutils = %{version}-%{release}" already.  If there is no way to tell the package manager to require a package _named_ coreutils, we can introduce an additional Provides for the "full" package that can be used for bootstrapping.
