python binding RPM packaging - "xrootd-python" vs "python2-xrootd"?

[jmuf]

The proper name for the xrootd python bindings seems disputed:
The "canonical" repo on http://xrootd.org/binaries/stable/slc/7/x86_64/ has "xrootd-python", but widely-used EPEL calls them "python2-xrootd" since

• Thu Aug 10 2017 Mattias Ellert mattias.ellert@physics.uu.se - 1:4.6.1-6
  • Rename python sub-package

and this of course can cause issues on machines that "see" both repositories.

The EPEL version is correct. See the platform guidelines for python package naming: https://fedoraproject.org/wiki/Packaging:Python. In addition to following the community guidelines, the EPEL style allows multiple python major versions (python2-xrootd, python3-xrootd).

Note the EPEL packaging takes backward compatibility into account: the package also has Provides: xrootd-python, meaning other package dependencies will continue to resolve.

It'd be useful for Xrootd to follow this change.
