"If you do not have sufficient privileges to carry out the steps above" could be
amended to add: ", or if you want limit access to the TeXLive fonts to
a particular

It would have been useful to mention this early on, but it is such an easy
thing to forget.   More useful info is "fc-list -v <fontname> | grep
"file", which
shows what fonts are found by fcontconfig.

That was the initial difficulty, but others were not able to reproduce
the problem because they had not add the TL fonts to fontconfig's
configuration (at which point the multiple instances bug is revealed).

On OS X the font manager allows you to check for duplicate fonts,
In cases where (presumably different versions of) the same fonts are
installed by the linux distro and TL, it would be useful to have a
simple mechanism to switch between distro and TL versions, check
for duplicates, etc.  The idea behind fontconfig is that it finds all the
fonts on the system and it is up to the application to choose, so in
the end TeX Live needs a way to give preference to fonts from
TL.

I like to know that TL is entirely contained in the TL tree.   When things go
wrong it is easy to rule out TL.
