Dear all,

HugoDoria's last two edits on the Spacewalk page 
(http://wiki.centos.org/HowTos/PackageManagement/Spacewalk) have removed 
line feeds from all preformatted text, as well as pointed to some RHEL6 
packages on a page written for CentOS 5.

I propose that the page be reverted backed to revision 82.

Regards,
Timothy
