The software described in this documentation is either no longer supported or is in extended support.
Oracle recommends that you upgrade to a current supported release.
This chapter describes how to create software channels in Spacewalk to which client systems can subscribe and obtain packages and errata. Each channel is associated with at least one repository, which defines the source of the packages and errata. The examples shown in this section are for the Unbreakable Linux Network (ULN) and the Oracle Linux yum server but you can use Spacewalk to obtain software packages from other external or internal sources.
