* Proposal owners:
** Modify comps to include nano Fedora wide.
** Create a new subpackage of <code>nano</code>, called
<code>nano-editor</code>.
** <code>nano-editor</code> to include
<code>/usr/lib/environment.d/10-nano.conf</code>, which sets
<code>$EDITOR</code> to <code>nano</code>.

With this approach, if <code>nano</code> is uninstalled, the
configuration will be removed with it. At the same time, installing
nano on its own won't install the conf.

Are you sure this will work? I just ran a test, and putting a new config file inside /usr/lib/environment.d only works for Gnome, and doesn't work for Mate, Cinnamon or SSH (tested by opening a terminal in the respective session and examining the environment variables). From what I gather in [1], systemd is not a standard way of interacting with the user's environment variables, and only Gnome has decided to use it. So this method of implementing this change seems to be making the default editor for Gnome be nano and not changing the defaults for anyone else.
