I just released mrepo 0.8.6 with RHEL 4.7's RHN/up2date code included which makes mrepo work on other distributions without requiring to copy those libraries.
Some of the highlights include:
- Support for RHEL5 and CentOS-5.
- Added YaST Online Update support.
- Added fuseiso support (root access no longer needed).
- Added unionfs support to merge ISOs to a single tree.
- Faster relinking of repositories.
- Caching of directory indexes to prevent regenerating repositories.
