This worries me as well, however the current syntax for constraints is confusing and error-prone. It would be great to be able to do something to make this easier to use, but exactly what it would be is hard to say. Making a change that would silently invert the functionality of existing configurations is, I agree, not a good idea. However, maybe it would be acceptable if a "version: 2" header is required in the document to enable the new syntax? Yet another option is to come up with some entirely new construct to supplement colocation and order which does what I think most people intuitively expects by default, which is enforces both colocation and ordering, so that 'foo depends on bar' means foo will start after bar, and only where bar is running. -- // Kristoffer Grönlund // kgronl...@suse.com
