I've put an updated version of the environmentmodule guidelines here:
https://fedoraproject.org/wiki/PackagingDrafts/EnvironmentModules
The main update is to take into account multiple module implementations. It also shifts the system module install path to /usr/share/modulefiles (and out of /etc).
Written up. Announcement text:
"""
The environment modules guidelines have been updated. The new guidelines mention how to deal with an alternate module implementation (lmod) and use the new %{_modulesdir} macro to shift modules from /etc/modulefiles to /usr/share/modulefiles (so that sysadmins can use the /etc/modulefiles location) See the policy for complete information:
