Hi,
I'm trying to define a Guix environment that enables the following LaTeX document to be compiled:

\documentclass[a4paper,12pt]{article}
\usepackage[utf8]{inputenc}
\usepackage[swedish]{babel}
\usepackage{url}
\usepackage{color}
\usepackage[colorlinks=true, linkcolor=blue, urlcolor=blue]{hyperref\
}
\usepackage[T1]{fontenc}
\usepackage{lmodern}
\usepackage{morefloats}
\usepackage{sectsty}
\usepackage{ifmtarg}
\usepackage{pagenote}

\makepagenote
\let\footnote\pagenote
\renewcommand*{\notedivision}{\section*{\notesname}}
\renewcommand*{\pagenotesubhead}[2]{}

\begin{document}

\title{\textsc{\Huge Curriculum Vitae\\[0.5cm]}}
\newpage

\setlength{\hoffset}{0pt}

\printnotes

\end{document}

It's a reduced version of the real document I'm writing. Right now I've packaged a bunch of things that were missing like texlive-generic-babel-swedish, texlive-morefloats, texlive-sectsty, texlive-ifmtarg and texlive-pagenote for an environment that is started with the following call:

$ ~/source/guix/main/pre-inst-env guix environment --ad-hoc texlive-base texlive-generic-babel-swedish texlive-url texlive-latex-hyperref texlive-fonts-ec texlive-lm texlive-morefloats texlive-sectsty texlive-pagenote

But I'm now stuck at the following error that pdflatex throws at me:

kpathsea: Running mktexpk --mfmode / --bdpi 600 --mag 1+0/600 --dpi 600 ec-lmr12
gsftopk: fatal: map file `psfonts.map' not found.
mktexpk: don't know how to create bitmap font for ec-lmr12.
mktexpk: perhaps ec-lmr12 is missing from the map file.
kpathsea: Appending font creation commands to missfont.log.
 )
!pdfTeX error: pdflatex (file ec-lmr12): Font ec-lmr12 at 600 not found
 ==> Fatal error occurred, no output PDF file produced!

I've looked at the Debian package and it looks to be provided by texlive-base: https://packages.debian.org/buster/all/texlive-base/filelist. The same folder path in Guix seems to be generated by the function gnu/packages/tex.scm:texlive-union; but I have no idea how I would go about having it generate the .map-file I want it to.

Does anyone happen to have any idea what to do here. I've spent a couple of hours without getting anywhere, so any hints would be appreciated.
