Busybox version of mktemp gives this error message: mktemp: Invalid argument I get that three times. Then I get non-existent directory error from line 65 but it is probably consequence of the previous errors. This the help for mktemp: " Usage: mktemp [-dt] [-p DIR] [TEMPLATE] Create a temporary file with name based on TEMPLATE and print its name. TEMPLATE must end with XXXXXX (e.g. [/dir/]nameXXXXXX). Without TEMPLATE, -t tmp.XXXXXX is assumed. -d Make directory, not file -q Fail silently on errors -t Prepend base directory name to TEMPLATE -p DIR Use DIR as a base directory (implies -t) -u Do not create anything; print a name Base directory is: -p DIR, else $TMPDIR, else /tmp " Use total six X's seems to fix the problem. /Jarkko
