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.
