bug#42166: texlive@2019 looks up font ‘.enc’ files in $PWD

["Ludovic Courtès" <ludovic.courtes@inria.fr>]

Hi!

I’m using texlive 20190410 on
<https://git.savannah.gnu.org/cgit/guix/maintenance.git/tree/talks/fosdem-2020/containers>
and pdftex fails like this:

not open encoding file for reading
 ==> Fatal error occurred, no output PDF file produced!
--8<---------------cut here---------------end--------------->8---

Stracing shows that pdflatex is looking for ‘fir_junpg2.enc’ in $PWD.

Any idea what’s going on?  This is with the monolithic ‘texlive’
package (I never managed to find the right package combination to use
the modular texlive).

I believe I used texlive@2018 (pre-core-updates merge) back when working
on this talk.

Thanks in advance,  :-)
