The engine is built without cgo, so a check by name missed a root group a name service holds or one number carrying another name: the root groups are resolved to numbers (now with kmem and shadow) and a number named nothing is refused for containers too. A group without write is granted nothing (§2). The look reads each path off the lock within five seconds, so a dead network mount cannot stop every health statement. A grant's account may not start with a dash. A group a record leaves for another asker is handed to it, so it is still taken back when the last asker goes (§5). The scheduler skips paths issue 339's guard refuses.
