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.
