Are two runs always required to generate a PDF when TEXMFCACHE is set? $ sudo su - $ mkdir -p /opt/context $ cd /opt/context $ wget http://lmtx.pragma-ade.nl/install-lmtx/context-linux-64.zip $ unzip *zip $ sh install.sh $ exit $ cat test.tex \starttext Test \stoptext $ export TEXMFCACHE=/tmp $ rm -rf $TEXMFCACHE/luatex-cache $ /opt/context/tex/texmf-linux-64/bin/mtxrun --autogenerate --script mtx-context --autopdf test.tex ... resolvers | resolving | remembered file 'mtx-context.lua' resolvers | resolving | remembered file 'mtx-contexts.lua' resolvers | resolving | remembered file 'mtx-context.lua' resolvers | resolving | remembered file 'mtx-t-mtx-context.lua' resolvers | resolving | remembered file 'mtx-t-mtx-contexts.lua' resolvers | resolving | remembered file 'mtx-t-mtx-context.lua' resolvers | resolving | remembered file 'mtx-context.lua' mtxrun | unknown script 'mtx-context.lua' or 'mtx-mtx-context.lua' $ /opt/context/tex/texmf-linux-64/bin/mtxrun --script context --version mtx-context | current version: 2021.04.10 17:09 $ mtxrun --autogenerate --script mtx-context --autopdf test.tex ... mkiv lua stats > runtime: 0.432 seconds, 1 processed pages, 1 shipped pages, 2.315 pages/second system | total runtime: 3.318 seconds of 3.372 seconds The first run fails; the second run succeeds. If TEXMFCACHE is not set, then the first run succeeds. If TEXMFCACHE is set to any non-empty value and $TEXMFCACHE/luatex-cache has not been created, mtxrun always terminates with the same unknown script error. What am I missing to ensure that ConTeXt will create luatex-cache in /tmp when TEXMFCACHE is set and successfully build the PDF on first run? Thank you!
