Subject: [bug#78424] [PATCH] gnu: texlive-libkpathsea: Add definitions for XDG paths.
Date: Wed, 14 May 2025 13:46:01 +0200

Without these paths set, if they are unset in the environment, jobs that need
to read from/write to TEXMFVAR or TEXMFCONFIG will fail.  If set, environment
variables take precedence.

* gnu/packages/tex.scm (texlive-libkpathsea): Add replacement, pointing to…
(texlive-libkpathsea/fixed): … this.  Add definitions for XDG_CACHE_HOME and
XDG_CONFIG_HOME.
