Then, I run `mtxrun --generate`, which exits instantly with the output
reported below. However, that is apparently not enough. I still get:

This sounds like a missing or misconfigured texmfcnf.lua (which should
be next to texmf.cnf).
This would need to be handled by the distribution (Alpine Linux devs).
Can you try to locate both files and share the contents? (There may
also be multiple copies of them.)
I report below the content of the two files, as they are in TeX Live
2020 (I have switched to `docker pull alpine`, as suggested in another
post, in which I can install Tex Live 2020).

% original texmf.cnf -- runtime path configuration file for kpathsea.
% Public domain.
% 
% If you modify this original file, YOUR CHANGES WILL BE LOST when it is
% updated.  Instead, put your changes -- and only your changes, not an
% entire copy! -- in ../../texmf.cnf.  That is, if this file is
% installed in /some/path/to/texlive/2020/texmf-dist/web2c/texmf.cnf,
% add your custom settings to /some/path/to/texlive/2020/texmf.cnf.
% (Below, we use YYYY in place of the specific year.)
% 
% What follows is a super-summary of what this .cnf file can
% contain. Please read the Kpathsea manual for more information.
%
% Each statement in this file boils down to:
%   <variable>[.<program>] [=] <value>
%
% Neither the <variable> nor the <value> may be empty.
% Any identifier (sticking to A-Za-z_ for names is safest) can be assigned.
% The `=' (and surrounding spaces) is optional.
% $foo (or ${foo}) in a value expands to the envvar or cnf value of foo.
% Lines can be continued with a \; no whitespace removal is done.
%
% Earlier entries (in the same or another file) override later ones, and
% an environment variable foo overrides any texmf.cnf definition of foo.
%
% All definitions are read before anything is expanded, so you can use
% variables before they are defined.
%
% If a variable assignment is qualified with `.PROGRAM', it is ignored
% unless the current executable (last filename component of argv[0]) is
% named PROGRAM.  This foo.PROGRAM construct is not recognized on the
% right-hand side. For environment variables, use FOO_PROGRAM.
%
% Which file formats use which paths for searches is described in the
% various programs' and the Kpathsea documentation (http://tug.org/kpathsea).
%
% // means to search subdirectories (recursively).
% A leading !! means to look only in the ls-R db, never on the disk.
% In this file, either ; or : can be used to separate path components.
% A leading/trailing/doubled path separator in the paths will be
%   expanded into the compile-time default. Probably not what you want.
%
% Brace notation is supported, for example: /usr/local/{mytex,othertex}
% expands to /usr/local/mytex:/usr/local/othertex.

% 
   Part 1: Search paths and directories.

% This is the parent directory of our several trees, i.e.,
% /usr/local/texlive/YYYY in the original TeX Live distribution.
%
% The path definitions here assume the directories are organized
% according to the TeX Directory Structure (http://tug.org/tds).
%
% Redistributors will probably want $SELFAUTODIR/share, i.e., /usr/share.
% Kpathsea sets (in kpathsea/progname.c):
% SELFAUTOLOC (directory of the binary=/usr/local/texlive/YYYY/bin/i386-linux),
% SELFAUTODIR (its parent = /usr/local/texlive/YYYY/bin), 
% SELFAUTOPARENT (its grandparent = /usr/local/texlive/YYYY), and
% SELFAUTOGRANDPARENT (its great-grandparent = /usr/local/texlive).
% Sorry for the off-by-one-generation names.

TEXMFSYSCONFIG = $TEXMFROOT/texmf-config

% Per-user texmf tree(s) -- organized per the TDS, as usual.  To define
% more than one per-user tree, set this to a list of directories in

%
% For texconfig to work properly, TEXMFCONFIG and TEXMFVAR should be named

% This main texmf.cnf file is installed, for a release YYYY, in a

% Since this file is subject to future updates, the TeX Live installer
% or human administrator may also create a file
% /usr/local/texlive/YYYY/texmf.cnf; any settings in this latter file
% will take precedence over the distributed one.
% 
% For security reasons, it is best not to include . in this path.
%
% The idea behind this lengthy definition: for each of
% SELFAUTO{LOC,DIR,PARENT}, look in the directory,
% then the subdirectories share/texmf-local, share/texmf-dist, share/texmf,
% then the subdirectories ./texmf-local, texmf-dist, ./texmf.
% At any given installation, most of these directories will not exist,
% but they all turn out to be useful somewhere.
% 
% Special addition -- we want to include one more directory: the
% great-grandparent's texmf-local, because that is how TL is installed
% by default.  That is, given a binary
% /usr/local/texlive/YYYY/bin/PLATFORM/kpsewhich, it should find
% /usr/local/texlive/texmf-local/web2c/texmf.cnf.  I.e., not under YYYY.
% 
% As a result, we cannot use actual brace expansion in the definition,
% since we don't want to scatter ../'s throughout the value.  Hence we
% explicitly list every directory.  Arguably more understandable anyway.

   Part 3: Array and other sizes for TeX, Metafont, etc.
%
% If you want to change some of these sizes only for a certain TeX
% variant, the usual dot notation works, e.g.,
% main_memory.hugetex = 20000000
%
% If a change here appears to be ignored, try redumping the format file.

% Memory. Must be less than 8,000,000 total.
%
% main_memory is relevant only to initex, extra_mem_* only to non-ini.
% Thus, have to redump the .fmt file after changing main_memory; to add
% to existing fmt files, increase extra_mem_*.  (To get an idea of how
% much, try \tracingstats=2 in your TeX source file;
% web2c/tests/memtest.tex might also be interesting.)
%
% To increase space for boxes (as might be needed by, e.g., PiCTeX),
% increase extra_mem_bot.
%
% For some xy-pic samples, you may need as much as 700000 words of memory.
% For the vast majority of documents, 60000 or less will do.

% Only values utf8 or utf-8 are meaningful. Other values are simply

% only, the value of command_line_encoding is irrelevant.

% file names in sources and DVI or XDV files are assumed to be UTF-8.
% Default is utf-8, from 2019-07-24, to assume UTF-8 file names.
% In order to switch off the function, define an environment variable:
