| === Packaging changes ===
| |
| | |
| Lots of effort has been done to cleanup the packages and to make them as complete, intuitive and modular as possible, allowing also external entities to reuse most of the infrastructure without the requirement to pull the whole stack in.
| |
| | |
| With the new package reorganization, users will find easier to update their cluster. The introduction of fence-agents and resource-agents packages will avoid the pain for users to restarts cluster nodes for simple scripts updates.
