Summary: os.tempnam fails on SUSE Linux to accept directory argument
Initial Comment:
On SUSE Linux 10.1 the function os.tempnam does not use
the "dir" argument properly. It always takes the
tmpdir, in this case "/tmp". In the example below it is
expected to get a filename of '/tmp/tmp/pref2iGGS5'
instead of '/tmp/pref2iGGS5'.

This behavior is also the same on the Python version
which comes with SUSE Linux 10.1. On Solaris 10 the
behavior is as expected, e.g.
-bash-3.00$ python

A patch for the test 'test_os.py' is attached to this
report. It has been tested on SUSE Linux 10.1.

Your hint about the environment variable TMPDIR
actually solves my problem. I have overlooked the
information given in the documentation about this fact.
Thanks.

This one once irritated me also.
In my case the cause was
the environment variable 'TMPDIR'.
This is the first location chosen
by os.tempnam (see 'man tempnam').
Please check again.
