The simplest way to do this is to use cobbler's replicate functionality.
cobbler replicate --master=[remote Genome Repo machine] --full-data-sync
For more advanced usage see the cobbler manpage.
Currently the use of cobbler replicate
requires the user to know the root password on the master cobbler server (the remote Repo machine). This is less than desirable but for now the default password is password.
Technically it is also possible to configure cobbler by hand. This obviously requires a more in depth understanding of cobbler and is outside the scope of this document.
