Hi, I am currently using mkiv and lmtx in parallel and noticed that both use the same texmf-cache subdirectory. Running: mtxrun --script cache --list gives mtx-cache | writable path: /home/adityam/texmf-cache/luatex-cache/context/5fe67e0bfe781ce0dde776fb1556f32e mtx-cache | mtx-cache | tma : 59 mtx-cache | tmc : 59 mtx-cache | rest : 35 mtx-cache | total : 153 mtx-cache | on both distributions. A consequence of this is that whenever I switch distributeions the font used in the document gets "compiled" and "dumped", i.e., I get messages: system > lua > compiling '/home/adityam/texmf-cache/luatex-cache/context/5fe67e0bfe781ce0dde776fb1556f32e/fonts/otl/lmroman12-regular.tma' into '/home/adityam/texmf-cache/luatex-cache/context/5fe67e0bfe781ce0dde776fb1556f32e/fonts/otl/lmroman12-regular.tmc' system > lua > dumping '/home/adityam/texmf-cache/luatex-cache/context/5fe67e0bfe781ce0dde776fb1556f32e/fonts/otl/lmroman12-regular.tma' into '/home/adityam/texmf-cache/luatex-cache/context/5fe67e0bfe781ce0dde776fb1556f32e/fonts/otl/lmroman12-regular.tmc' stripped fonts > otf loading > loading '/opt/context-minimals/texmf/fonts/opentype/public/lm/lmroman12-regular.otf', hash 'lmroman12-regular' Is there a way to avoid that? I can, of course, set different values of TEXMFCACHE for both distributions, but does it make sense to to use a different hash (5fe67e...) for the two? Thanks, Aditya
