I don't think signals to the container init process is the answer. You can run a single program in a container. When that program reaches a certain state, it could report that it is operational. I don't know what the correct way to do that report using a new lxc feature.
Currently, my program creates a file that indicates it is operational. My container start-up code looks for that file before it assumes that the container is ready. Regards.

Any ideas? May one send signals to the container's init process? ------------------------------------------------------------------------------ Learn Graph Databases - Download FREE O'Reilly Book "Graph Databases" is the definitive new guide to graph databases and their applications.
