Bug 840250

Description of problem:
Deploying configuration file which path comprises symlink fails.

Version-Release number of selected component (if applicable):
Spacewalk 1.7

How reproducible:
100%

Steps to Reproduce:
1. Register System to Satellite
2. Install rhncfg* on the System
3. rhn-actions-control --enable-all
4. Create configuratoin channel with the following files in it.
    directory - /opt/test_folder
    symlink   - /root/test_dir/link_to_test_folder -> /opt/test_dir
    file      - /root/test_dir/link_to_test_dir/test_file

5. Add the configuration channel to the System
6. Schedule deploy of all files from the configuration channel to the System
7. rhn_check -vv

Intention: link home directory of user to a large disk which is mounted on /opt, deploy user specific files (.bash_profile, etc) to /home/$USER since effective mount point of the large disk is subject to change.
On my System:

works like a charm.

when dir/symlink/file are up-to-date, "deploy all config files" works:

D: do_call configfiles.deploy({'files': [{'config_channel': 'x-env-test-debug', 'username': 'spw-test', 'encoding': '', 'checksum': '', 'filetype': 'directory', 'delim_start': '', 'modified': '', 'symlink': '', 'groupname': 'spw-test', 'delim_end': '', 'selinux_ctx': '', 'filemode': 644, 'file_contents': '', 'checksum_type': '', 'path': '/opt/spw-test', 'revision': 1}, {'config_channel': 'x-env-test-debug', 'username': '', 'encoding': '', 'checksum': '', 'filetype': 'symlink', 'delim_start': '', 'modified': '', 'symlink': '/opt/spw-test', 'groupname': '', 'delim_end': '', 'selinux_ctx': '', 'filemode': '', 'file_contents': '', 'checksum_type': '', 'path': '/home/spw-test', 'revision': 1}, {'config_channel': 'x-env-test-debug', 'username': 'spw-test', 'encoding': 'base64', 'checksum': 'ca78bb4bb4901e6ba30170b348056f8b', 'filetype': 'file', 'delim_start': '{|', 'modified': '', 'symlink': '', 'groupname': 'spw-test', 'delim_end': '|}', 'selinux_ctx': '', 'filemode': 644, 'file_contents': 'IyBTcGFjZXdhbGsgbWFuYWdlZAojCiMgLmJhc2hfcHJvZmlsZQoKIyBHZXQgdGhlIGFsaWFzZXMg\nYW5kIGZ1bmN0aW9ucwppZiBbIC1mIH4vLmJhc2hyYyBdOyB0aGVuCgkuIH4vLmJhc2hyYwpmaQoK\nIyBVc2VyIHNwZWNpZmljIGVudmlyb25tZW50IGFuZCBzdGFydHVwIHByb2dyYW1zCgpQQVRIPSRQ\nQVRIOiRIT01FL2JpbgoKZXhwb3J0IFBBVEgKdW5zZXQgVVNFUk5BTUUK\n', 'checksum_type': 'md5', 'path': '/home/spw-test/.bash_profile', 'revision': 1}]},){'cache_only': None}

also adding /home/spw-test/.bashrc to channel works:
