I'm getting close to deploying this with:

- /usr/share/modulefiles being the new default system path.  Both
environment-modules and Lmod will have /usr/share/Modules/modulefiles in
their default MODULEPATH for a bit to help with transition.

- Both with provide "environment(modules)" which module using packages
should require.

However, I'm running into problems converting environment-modules to
alternatives.  /etc/profile.d/modules.sh is currently a file and it does
not get converted to a link by update-alternatives on upgrade.  Any ideas?

https://fedoraproject.org/wiki/PackagingDrafts/UsingAlternatives does
not seem to mention any issues like this.

I've attached the spec I'm trying to update to.  I'm afraid I'm going to
need some kind of %pre/%pretrans script to handle this.

%description
The Environment Modules package provides for the dynamic modification of
a user's environment via modulefiles.

Each modulefile contains the information needed to configure the shell
for an application. Once the Modules package is initialized, the
environment can be modified on a per-module basis using the module
command which interprets modulefiles. Typically modulefiles instruct
the module command to alter or set shell environment variables such as
PATH, MANPATH, etc. modulefiles may be shared by many users on a system
and users may have their own collection to supplement or replace the
shared modulefiles.

Modules can be loaded and unloaded dynamically and atomically, in an
clean fashion. All popular shells are supported, including bash, ksh,
zsh, sh, csh, tcsh, as well as some scripting languages such as perl.

Modules are useful in managing different versions of applications.
Modules can also be bundled into metamodules that will load an entire
suite of different applications.

NOTE: You will need to get a new shell after installing this package to
have access to the module alias.
