mrepo builds a local APT/Yum RPM repository from local ISO files, downloaded updates, and extra packages from 3rd party repositories. It takes care of setting up the ISO files, downloading the RPMs, configuring HTTP access and providing PXE/TFTP resources for remote network installations.
It was primarily intended for doing remote network installations of various distributions from a laptop without the need for CD media or floppies, but is equally suitable for an organisation’s centralized update server. Doing a remote installation only requires a configured DHCP-server, the TFTP service and a Webserver configured with mrepo. Then boot your system using a PXE-enabled network card.
For updating your local systems, configure either Smart, Apt, Yum or up2date and point them to your local mrepo server.
