As an example, take the checkpoint service. The checkpoint service today sends messages and receives responses via the coroapi. This could be changed to depend on the cpg service instead to provide the same messaging semantics. Checkpoints have some timer dependencies, in which case a package such as libqb could be used (to provide poll based timers) or the current timer/poll implementation could be copied from corosync. The ckpt.c code that is currently a service engine could then be reworked to act as its own daemon. All services could be handled in this way. To handle synchronization, the cpg sync api could be used as was proposed at the recent linux plumbers conf.
