Prior to the release of a new version, […] Read more

Why we use Cfengine: file editing

Here at Normation, we use Cfengine 3 extensively for configuration management across Linux and Windows servers. A question we get often is why Cfengine? I’d like to focus this post on file editing.

Cfengine tip: Keeping cf-execd alive (whatever happens)
