We at SuSE use "quilt" to manage patches, and build scripts around it to automate, if required. This simplifies the task if there are variations in build, and management. > I believe one should not apply the patches frequently on production > servers, unless you really require them and recognise to fix a flaw. On You are right. Quite often, patches bring in new bugs. So the rule of thumb is, if it works, leave it alone. > security side, none of our boxes is directly connected to insecure > network and there are separate firewall devices to take care of external > threats.

As for the rest, if it breaks, you fix it. The rest of the patches usually come as feature requests (and starting another cycle of introducing new bugs! :) ), and are requests by other developers/users who cant get a workaround, and badly need it. Answering your question, it is a good idea to categorize your patches in what you need and what you don't before you apply them. > > Please share some information, how you manage production servers in > terms of OS patches, frequency of applying them, how much old patches > generally are applied? > This is more often an internal system admin policy, and I know this is what you wish to know more about. It is usually a test, break, fix cycle on a test machine, before going into production. All in all, it varies from company to company. -- Goldwyn _______________________________________________ ilugd mailinglist -- ilugd@lists.linux-delhi.org http://frodo.hserus.net/mailman/listinfo/ilugd Next Event: http://freed.in - September 28-29, 2007 Archives at: http://news.gmane.org/gmane.user-groups.linux.delhi http://www.mail-archive.com/ilugd@lists.linux-delhi.org/
