Description of problem:
In Satellite 5.3, user can still create custom kickstart distributions like in 5.2, however the Tree Path needs to be local to the satellite.  If user has an external kickstart tree location via http they need to set variables indicating server and path in the kickstart distro, and use --url in the kickstart profiles.  User is unable to use the existing http_server and media_path variables since that would make kickstart update the pkgs in %post from the remote location instead of from Satellite, which will fail.  Cobbler should use $redhat_management_server variable for the following step instead of $http_server -
wget -P /tmp/rhn_rpms/optional http://$http_server/download/package/7b86b444ab21fd3b237fd9c1a965baeae73a3c2e/0/3/19787/libxml2-python-2.6.26-2.1.2.8.x86_64.rpm http://$http_server/download/package/036d5749799616fb29ae889c393f1d49bbbe839d/0/3/5672/rhnlib-2.2.7-2.el5.noarch.rpm http://$http_server/download/package/8932277b32cac41e3a7c538e2956409c88622ed4/0/3/16519/pyOpenSSL-0.6-1.p24.7.2.2.x86_64.rpm

Version-Release number of selected component (if applicable):
Red Hat Network (RHN) Satellite 5.3.0

How reproducible:
Always.

Steps to Reproduce:
1. Have a server SERVER1 with a copy of a ks tree;
2. Have a 5.3.0 satellite with a custom ks distro, set Tree Path to some local ks tree path, and under Variables set http_server=SERVER1 and media_path=PATHTOKSTREE
3. Create kickstart profile using this distro
4. Try to kickstart a system with this distro

Actual results:
The %post script that downloads newer copies of things like pyOpenSsl won't work since that needs to be requested from the satellite, not SERVER1.

Expected results:
Updating http_server should not impact the %post script above.

Additional info:
Filing bug per discussion with Justin (thanks!).  Workaround is as follows:

1. Update the ks distros and first change Tree Path from the http://url to local ks tree on Satellite - e.g., /var/satellite/rhn/kickstart/rhel-x86_64-server-5-u3
2. Under "Variables" tab in the distro, add 2 variables - http_server2 and media_path2 - to specify the alternative server and path that they used to specify in the Tree Path. E.g.,
http_server2=SERVER1
media_path2=/pub/kickstart/dist/rhel-x86_64-server-5-u3
3. Now for all ks profiles using these distros, set url option in Advanced Options to "--url $http_server2$media_path2"
4. After saving the distros and ks profiles, wait a few minutes so taskomatic can sync the ks data with cobbler.
