I used a manual (tlmgr) installation of texlive-2016 on gentoo linux, after removing this and installing the texlive-2017 from the distribution I get ` Package pgf Error: Driver file ``pgfsys-luatex.def'' not found.. ...{Driver file ``\pgfsysdriver'' not found.}}` as described in https://sourceforge.net/p/pgf/bugs/384/ Minimal working example: \documentclass{article} \usepackage{graphicx} \makeatletter\show\Gin@driver \usepackage{tikz} \begin{document} \end{document} Was this bug fixed in the tlmgr-texlive-2016 and made it back into the distribution texlive-2017?
find /usr -name "pgfsys-luatex.def" could not find a matching file. other systems install it to /usr/local/texlive/2017/texmf-dist/tex/generic/pgf/systemlayer/pgfsys-luatex.def http://www.portagefilelist.de/ could not locate it too.
I have /usr/share/texmf-site/tex/generic/pgf/systemlayer/pgfsys-luatex.def here maybe your pgf install is broken ?
Can find the package now with pfl. merged dev-tex/pgf-3.0.1-r1 and it works now. must have been a problem on my system. Sorry for the noise.
