Ceph

python setuptools v61 changed package discovery so that if it finds what it thinks are multiple top-level packages in a directory, it will fail to build. This was introduced by https://github.com/pypa/setuptools/pull/3177, and causes the ceph RPM build to fail with:

...
[ 9562s] error: Multiple top-level packages discovered in a flat-layout: ['top', 'CMakeFiles'].
[ 9562s] 
[ 9562s] To avoid accidental inclusion of unwanted files or directories,
[ 9562s] setuptools will not proceed with this build.
[ 9562s] 
[ 9562s] If you are trying to create a single distribution with multiple packages
[ 9562s] on purpose, you should not rely on automatic discovery.
[ 9562s] Instead, consider the following options:
[ 9562s] 
[ 9562s] 1. set up custom discovery (`find` directive with `include` or `exclude`)
[ 9562s] 2. use a `src-layout`
[ 9562s] 3. explicitly set `py_modules` or `packages` with a list of names
[ 9562s] 
[ 9562s] To find more information, look for "package discovery" on setuptools docs.

[ 9833s] RPM build errors:

This has been fixed in Fedora downstream by moving a/src/tools/cephfs/cephfs-shell to a separate subdirectory (see https://src.fedoraproject.org/rpms/ceph/blob/rawhide/f/0021-cephfs-shell.patch). I've confirmed this approach also works for openSUSE.
