texlive 2016 was installed locally in
/usr/local/texlive/2016/ on a gentoo Linux system by the
install-tl -gui installer.
An update with
/usr/local/texlive/2016/bin/x86_64-linux# ./tlmgr update --all [..] Transcript written on xelatex.log. fmtutil [INFO]: /var/lib/texmf/web2c/xetex/xelatex.fmt installed. fmtutil [WARNING]: inifile csplain.ini for pdfcsplain/xetex not found. fmtutil [INFO]: Disabled formats: 6 fmtutil [INFO]: Successfully rebuilt formats: 3 fmtutil [INFO]: Not selected formats: 40 fmtutil [INFO]: Failed to build: 1 (xetex/pdfcsplain) fmtutil [INFO]: Total formats: 50 fmtutil [INFO]: exiting with status 1
I wonder that texlive installs files outside
/var/lib/texmf/web2c/xetex/xelatex.fmt is usually entrusted to the package manager of the operating system. I fear this could raise conflicts with the package manager.
Is this a bug? Is there a variable I missed to set with the result that TL installs into the wrong folder?
