Subject: [PATCH core-updates 2/3] gnu: texlive-amsfonts: Adjust to build with
 texlive-updmap.cfg.
Date: Thu, 14 Jan 2021 13:41:26 -0500

* gnu/packages/tex.scm (texlive-amsfonts)[phases]
{build-fonts}: Do not set SOURCE_DATE_EPOCH, already done by the build
system.  Let resources be auto-discovered by TeX Live machinery by simply
setting GUIX_TEXMF.  Remove references to the texlive-union input.  Remove
trailing #t.
{install-generated-fonts}: Remove trailing #t.
[native-inputs]: Replace texlive-union by texlive-updmap.cfg.  Remove the
texlive-cm and texlive-metafont arguments of texlive-updmap.cfg.
