Hi,

i'm building a small document with LuaLaTeX, for that i have use the
following manifest

--8<---------------cut here---------------start------------->8---
(specifications->manifest
  (list
    "texlive-amsmath"
    "texlive-todonotes"
    "texlive-xpatch"
    "texlive-collection-luatex"
    "texlive-collection-basic"
    "texlive-latexmk"
    "texlive-scheme-basic"
    "texlive-biber"
    "texlive-booktabs"
    "texlive-microtype"
    "texlive-koma-script"
    "texlive-lipsum"
    "texlive-pgfplots"
    "texlive-biblatex"))
--8<---------------cut here---------------end--------------->8---

This command takes quite a long time
--8<---------------cut here---------------start------------->8---
guix time-machine --commit=21b718f4d6c3ded8ef50d12f6e9ae6474f74620f \
       shell --manifest=guix.scm -- latexmk -lualatex -auxdir=.tex-cache main
--8<---------------cut here---------------end--------------->8---

To be precise:
--8<---------------cut here---------------start------------->8---

Running `latexmk -lualatex -auxdir=.tex-cache main` takes under 10
seconds.  These times are for fresh builds, i.e. the intermediate files
have been removed.  Still even recompilation is many times slower with
guix provided LuaLaTeX than it is on Arch.  I should also note, that
using the modular TeX packages actually helps here, with the full
TeXlive package the compilation time is nearly twice as much.

Another thing i noticed is, that a directory with the following
structure gets created:

This is obviously for caching purposes, but (seemingly random) having a
folder named '{' in your working directory certainly is confusing.
