I have successfully executed the requests to create a bucket and create
an on RHEL 6.2 using boto. Here are few a minor tweaks that I noted
during the process:
(1) In the CloudScape home, there is a minor typo in that INSTALL.txt. I
think 'sh-keygen -t rsa -q' should be 'ssh-keygen -t rsa -q'
(2) Another trivial tweak I required for RHEL in the
'cloudstack-aws-api-register' script I changed
#!/cygdrive/c/python26/python to match my python path of #!/usr/bin/python
(3) I needed to set 'enable.ec2.api' to true before running the boto
commands

The s3-hdfs branch in git.cloud.com [1] replaces the filesystem backend
with a HDFS backend.
Since we're still discussing where development happens, I haven't moved it
to anywhere official.
For those looking to integrate other storage backends, it might provide a
useful guide.
The steps to get this working are the same, except that the storage.root
in step 4 below is as follows:
storage.root=hdfs://<hdfs namenode>:9000/s3
On the HDFS side, I used Hadoop 0.23.1 (although I think it should work
with Hadoop 1.0).
I found that I had to set the following configuration in hdfs-site.xml
<property>
<name>dfs.permissions</name>
<value>false</value>
</property>
