Ah, this will be better. I've got so much time in figuring out this fontconfig in the first place, I didn't think about the conf.d. Reference from 50-user.conf:
<!--
Load per-user customization files where stored on XDG Base Directory
specification compliant places. it should be usually:
$HOME/.config/fontconfig/conf.d
$HOME/.config/fontconfig/fonts.conf
-->
<include ignore_missing="yes" prefix="xdg">fontconfig/conf.d</include>
<include ignore_missing="yes" prefix="xdg">fontconfig/fonts.conf</include>
Looking at /etc/fonts/conf.d/README:
Files begining with: Contain:
00 through 09 Font directories
10 through 19 system rendering defaults (AA, etc)
20 through 29 font rendering options
30 through 39 family substitution
40 through 49 generic identification, map family->generic
50 through 59 alternate config file loading
60 through 69 generic aliases, map generic->family
70 through 79 select font (adjust which fonts are available)
80 through 89 match target="scan" (modify scanned patterns)
90 through 99 font synthesis
Starting the filename with 10 isn't correct. The Arch packages use a fontconfig starting with 35. I'd like to make the provided fontconfig file usable for both user-only and system-wide installs.
This blocks #9

DejaVu uses 57 and 58:
57-dejavu-sans.conf
57-dejavu-sans-mono.conf
57-dejavu-serif.conf
58-dejavu-lgc-sans.conf
58-dejavu-lgc-sans-mono.conf
58-dejavu-lgc-serif.conf
Perhaps it should be 56? 59? 71? Since I created an "emoji" generic family, perhaps it makes sense to separate it into two files at 35 and 59?
@edgemaster: Any thoughts? Why did you select 35 for the fontconfig filename? I'm doing some tests now and 35 works with fc-match -s for "sans" and "emoji", but not correctly for "Bitstream Vera Sans". Well, I've figured a place to implement unit tests and/or travis.ci! Hmm... The current file works correctly at 56.

I picked 35 as a bit of a guess, and roughly following the hints given in the fontconfig system readme.
Arch ships the default font config files with the patches at https://projects.archlinux.org/svntogit/packages.git/tree/trunk?h=packages/fontconfig
I'm not sure if other fonts diverge from other standard configs.
It is the priority of the config file I was referring to previously when I said that I needed to test the arch system install further. I didn't have the time you track down/run through test cases for each of the relevant configuration bugs though.
I seem to remember that there's some oddity with other font priorities relative to the user configuration priority also.
Need to compare with Debian/Ubuntu to see how the distributions differ.

Ah ha! I will figure out a good way to do automated testing to make it easier to confirm.

This looks good enough for confirming correct installation:
$ fc-match -s sans | head -n2
Vera.ttf: "Bitstream Vera Sans" "Roman"
EmojiOneColor-SVGinOT.ttf: "Emoji One Color" "Regular"
$ fc-match -s serif | head -n2
VeraSe.ttf: "Bitstream Vera Serif" "Roman"
EmojiOneColor-SVGinOT.ttf: "Emoji One Color" "Regular"
$ fc-match -s "Emoji One Color" | head -n2
EmojiOneColor-SVGinOT.ttf: "Emoji One Color" "Regular"
Vera.ttf: "Bitstream Vera Sans" "Roman"
$ fc-match -s "Bitstream Vera Sans" | head -n2
Vera.ttf: "Bitstream Vera Sans" "Roman"
EmojiOneColor-SVGinOT.ttf: "Emoji One Color" "Regular"
$ fc-match -s mono | head -n2
VeraMono.ttf: "Bitstream Vera Sans Mono" "Roman"
EmojiOneColor-SVGinOT.ttf: "Emoji One Color" "Regular"
$ fc-match -s monospace | head -n2
VeraMono.ttf: "Bitstream Vera Sans Mono" "Roman"
EmojiOneColor-SVGinOT.ttf: "Emoji One Color" "Regular"
I'm going to automate it into a tests.sh

@edgemaster I've made a tests.sh to do some "unit tests". It compares a diff of current fc-match -s "$FONT" | head -n2 results to expected results. The output on my machine:

Awesome. I'll give it a whirl and see how tweaking the priority of the configuration file impacts things.

I've changed the file to 56-emojione-color.conf since it passes all of the tests in test.sh correctly.
The user installer has been updated to put the file in $HOME/.config/fontconfig/conf.d/. This also works for system-wide install.
@frederik-elwert I still need to backup the user's existing font.conf for backwards compatibility. Let me know if you can think of any better way to handle the upgrade process. Maybe I could get crazy and hash the file? Seems overkill.

Installing at 56 causes many fonts in Firefox to become Bitstream, even when specified to be otherwise.
For example, the UI flow of the GitHub webpages is broken with Bitstream.
Trying to work out how CSS font selectors interact with the system fallbacks...
