It will setup the container

This command is mainly used when you want to quickly launch an

<command>lxc-execute</command> command will run the
specified command into the container via an intermediate
process, <command>lxc-init</command>.
This lxc-init after launching the specified command,
will wait for its end and all other reparented processes.
(to support daemons in the container).
In other words, in the
container, <command>lxc-init</command> has the pid 1 and the
first process of the application has the pid 2.

<command>lxc-execute</command>명령어는 컨테이너 내부에서 <command>lxc-init</command> 프로세스를 통해 지정한 명령어를 실행한다.
<command>lxc-init</command>은 지정한 명령어를 실행한 뒤에, 해당 명령어 및 그 명령어에서 실행된 모든 프로세스들을 기다린다(컨테이너 내에서 데몬을 지원하기 위한 것).
즉, 컨테이너내에서 <command>lxc-init</command>는 pid는 1이 되고, 그 다음으로 실행되는 응용 프로그램은 pid가 2가 된다.

The above <command>lxc-init</command> is designed to forward received
