Description of problem:
When kickstart installing a server with spacewalk it does not automatically register the machine with spacewalk.
In the ks-post.log on the kickstarted machine you can see that it does a wget of rhnlib into /tmp/rhn_rpms/ but afterwards tries to install /tmp/rhn_rpms/optional/rhnlib*

looking in git i saw this file:
http://git.fedorahosted.org/git/spacewalk.git?p=spacewalk.git;a=blob;f=java/code/src/com/redhat/rhn/manager/kickstart/KickstartFormatter.java;h=b0f09fa3c7ea57ff48eb04a54a349b1e91f9c9c4;hb=HEAD

you can see this is hardcoded in this file.

The output in %post of the kickstart file should look like this:


wget -P /tmp/rhn_rpms/optional http://spacewalk.example.com:80/download/package/26171069417ca55058d3a66a240880ced67d6c46/0/2/981/libxml2-python-2.6.26-2.1.2.7.i386.rpm http://spacewalk.example.com:80/download/package/2e9baaa44ea1132336e8ba9d4e53d3065ea0ccd2/0/2/2369/pyOpenSSL-0.6-1.p24.7.2.2.i386.rpm http://spacewalk.example.com:80/download/package/bcb625ead9fb059bd49e9268be3b4297fc5400f8/0/2/6052/rhnlib-2.5.10-1.el5.noarch.rpm

rpm -Uvh --replacepkgs --replacefiles /tmp/rhn_rpms/optional/pyOpenSSL* /tmp/rhn_rpms/optional/rhnlib* /tmp/rhn_rpms/optional/libxml2-python*


How reproducible:
-make a kickstart install
-this machine will not register itself inside spacewalk
-have a look inside ks-post.log
-you'll see this error:  error: File not found by glob: /tmp/rhn_rpms/optional/rhnlib*


Expected results:
when i changed the lines by hand -as pasted above- it installs rhnlib correctly and immediately registers my machine inside spacewalk.
