Redirect command output to config file without make it background

After executing "make" at client_test/python/ceph_tests,
s3-tests/s3test.conf is empty and all tests fail.

Behaiviour of "&>" seems to be dependent on shells.

On Ubuntu Linux 12.10:

bash: output is redirected
$ bash -c 'echo hoge &> out.txt'
$ cat out.txt
hoge

zsh: output is redirected
$ rm out.txt
$ zsh -c 'echo hoge &> out.txt'
$ cat out.txt
hoge

sh: output is shown in stdout and out.txt remains empty
$ rm out.txt
$ sh -c 'echo hoge &> out.txt'
hoge
$ cat out.txt
