I disagree. I have about 12 different modules, any combination of which may be applied to a given system, all of which need to ensure that sshd is installed and running on a system. They all have a single, common need. However, some of those modules also run on systems where we don't need to ensure that sshd is running. The solution to this is an interlocking maze of module dependancies which is downright terrifying. You can't import because of redefinitions. You yourself know well and deeply the issues involved with calling the same class from different places with different parameters. It is nearly impossible to get there from here. The ability for puppet to say "oh, I've seen this definition before and it's exactly the same so that's not an error" would be a tremendous improvement. > That's not to deny that there is room for Puppet to improve here, but > I suspect there is less room than you suppose. I did an intensive deep dive on the current puppet code base regarding this issue, and my diagnosis was that it was currently impossible without a complete rewrite of the dependency hierarchy, and likely the addition of a third phase between the current two to improve this situation. Assuming I am right, this is a major overhaul. -- Jo Rhett Net Consonance : consonant endings by net philanthropy, open source and other randomness -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
