Quattor can greatly help with OS errata deployment. QWG templates has a few specific features and tools to help managing them.

Downloading OS Errata

Errata should normally be downloaded from the official public servers for the distribution you use. With Scientitific Linux it is possible to use rsync to syncrhonize a local directory with the official repository. The rsync official URL prefix is:

• For SL4:

  rsync://rsync.scientificlinux.org/scientific/VERSION/ARCH/errata/SL/RPMS/
  

• For SL5:

  rsync://rsync.scientificlinux.org/scientific/VERSION/ARCH/updates/security
  

GRIF tends to have a rather up-to-date mirror of these repositories that you can access with http at:

http://quattorsrv.lal.in2p3.fr/packages/os/VERSION/errata

These are just suggestions, there are many way to synchronize with a reference repository, including YUM and a script provided by SCDB, utils/misc/sync-os-errata, to do it in a cron job using rsync or wget.
