[NTG-context] minimal update problem

Hi, I am using context minimal on a linux box. After I created a directory named "texmf-local" under $TEXMFROOT and run command: ctxtools --updatecontext All downloaded files went to texmf-local and no update to the folder texmf-context. I do not like this way of updating, because I keep personal data/file in texmf-local. Can anybody tell me how to avoid such problem? -- Zhaopeng XING Tinbergen Institute
