Uyuni Proxy caches packages in the /var/cache/ directory. If there is not enough space available in /var/cache/, the proxy will remove old, unused packages and replace them with newer packages.

As a result of this behavior:

  • The larger /var/cache/ directory is on the proxy, the less traffic there will be between it and the Uyuni Server.

  • By making the /var/cache/ directory on the proxy the same size as /var/spacewalk/ on the Uyuni Server, you avoid a large amount of traffic after the first synchronization.

  • The /var/cache/ directory can be small on the Uyuni Server compared to the proxy. For a guide to size estimation, see the [server-hardware-requirements] section.
