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.
          If the root user's umask
          is too restrictive (for example, 0077 or similar instead of
          0022), Apache, Tomcat, and Java processes cannot read some
          files written during Spacewalk installation or written by
          commands such as spacewalk-repo-sync or
          spacecmd. Clients might also stop working
          because Spacewalk cannot serve yum metadata or package files.
