How this works

When a program is executed, we check if we have some capabilities sets related to it (directly or inherited). If we have, we check for set tagged with the correct uid or the default flag. If we have both, we take the one tagged with the uid. If we have none, the same check is done with the parent directory, and so on until a capabilities set is found. If none are found, the capabilities set will be empty.
