[Fedora-packaging] environment module alternatives

Packaging (and mpi folks as they are the main users of modules) - In addition to the current environment-modules package in Fedora, there is at least one other implementation of the "environment modules" system - Lmod. This is Lua based rather than C/TCL based but can handle the TCL based module file format as well as a lua based format with a .lua extension. There is also the pure TCL version of environment-modules which some seem to prefer. I'd like to package Lmod for Fedora as well. My current plan is to use alternatives for the /etc/profile.d/modules.* links in order to allow both to coexist. I think we also want to move the current /usr/share/Modules/modulefiles system module file location to /usr/share/modulefiles (which would be owned by both environment-modules and Lmod). That way either package can make use of the modulefiles installed by other packages. environment-modules currently ships some sample modules which I'm not yet sure should stay in /usr/share/Modules/modulefiles (and only be used by it) or if they should get moved to /usr/share/modulefiles for Lmod's use as well (some are generic, some specific to environment-modules) We also would need some kind of virtual provide I believe for module using packages to require instead of the current "environment-modules". Perhaps environment-modules(system) or environment(modules)? Suggestions welcome.
