You could run Ubuntu server, or Centos if you were averse to paying for you linux distro or go the whole hog and do the Redhat thing and get support. We have ~150 Redhat servers and use Satellite to roll out updates/security/patches/config > Im curious about this.

It is creeping into the desktop space. We've deployed 250 Redhat desktops in the last year and then the server infrastructure to support them. > Thoughts? many ... where do you want to start ;) cheers, Kim -- Operating Systems, Services and Operations Information Technology Services, The University of Adelaide [EMAIL PROTECTED] -- ubuntu-au mailing list ubuntu-au@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-au
