Howdy, Today's update via tlmgr ran fmtutil-sys --byfmt pdfcsplain ... without the --no-error-if-no-format and failed when running luatex -ini -jobname=pdfcsplain -progname=pdfcsplain -etex luaplain.ini' ... and I assume that's not a real problem? Good Luck, Herb Schulz (herbs at wideopenwest dot com)
