There are both good points and bad points to that analogy, Jim. Unfortunately, the whole Service Pack moniker has received something of a black eye. But, at the same time, the quarterly update rollups have their own warts, too. The problem becomes one of a forced update to the equivalent of a Service Pack quite a bit sooner than Microsoft does with its Service Packs. "If you want Security Update X for your system, you must update to Service Pack Y" first type things; the RHEL setup can force the use of the updates sooner than Microsoft would dare, and the CentOS echo forces it within a week (unless I'm missing a way to tell yum "grab security updates, but leave the Quarterly alone for now"). But, then again, MS's Service Packs tend to break a great many more things than RHEL quarterly updates do. But they come out less frequently. The big sticker is the size of the updates. Of course, RHEL Updates are shipped out on physical media if required, right? If MS required users, in order to stay updated, to download ~600MB every quarter, the outrage would be significant. -- Lamar Owen Director of Information Technology Pisgah Astronomical Research Institute 1 PARI Drive Rosman, NC 28772 (828)862-5554 www.pari.edu
