nspawn: optionally run a stub init process as PID 1 This adds a new switch --as-pid2, which allows running commands as PID 2, while a stub init process is run as PID 1. This is useful in order to run arbitrary commands in a container, as PID1's semantics are different from all other processes regarding reaping of unknown children or signal handling. 2016-02-03 20:32:06 +01:00			`#pragma once`

nspawn: flush out environment block of the -a stub init process The container detection code in virt.c we ship checks for /proc/1/environ, looking for "container=" in it. Let's make sure our "-a" init stub exposes that correctly. Without this "systemd-detect-virt" run in a "-a" container won't detect that it is being run in a container. 2016-12-06 18:19:23 +01:00			`#include "sd-id128.h"`
