When it comes to editing files in-place, you'll get different answers from people depending on what they use. I used editfiles in cfengine2, which I thought were quite powerful. Some people think that editing files in-place is a horrible idea, mostly because there are always corner cases where data are lost. They'll say it's better to just push down whole files. I tend to agree now, after being bit by the concequences of a poor edit. Some CF software lets you use templates (I know bcfg2 and puppet do) which can get around the need to keep every variant of file on hand. I use templates now, but I still wish I could use editfiles to modify but otherwise keep the content of a config file. I'm impressed with Augeas (http://augeas.net/), which I believe Puppet is now using. It provides an API to edit any configuration file, as long as you have one of the Augeas specifications (or lens in Augeas-speak) for that file. There are Ruby bindings so Puppet can use the library natively. Unfortunately, it means that you have yet another dependency and DSL to learn when creating novel lenses. -- Jonathan Billings <billi...@negate.org> _______________________________________________ Discuss mailing list Discuss@lopsa.org http://lopsa.org/cgi-bin/mailman/listinfo/discuss This list provided by the League of Professional System Administrators http://lopsa.org/
