That was quick.

Okay. I see that commit on master.
Building again, however, the original problem persists:

    ! Font U/euf/m/n/10=eufm10 at 10.0pt not loadable: Metric (TFM) file not found.

The new texlive-amsfonts/fixed don't need to list eufm10 targets?

Both of those files-differ? invocations do indeed return empty lists for me. As a
sanity check, I re-confirmed that the document typesets within a texlive --pure
environment. So what gives?

$ guix time-machine --commit=4821e3eb4edd532bb236973a986e609634d0ab28 -- shell --pure texlive findutils
bash-5.1$ find -L $GUIX_ENVIRONMENT -name '*eufm10*'

but...

$ ./pre-inst-env guix shell texlive-asmfosnts  # on commit fad6a742351a599219dabcd152327afc39e4e3cf

Is my package definition just missing something obvious?
