When the parent of the first process dies, the container stays there
making very difficuly to track it and to kill. We have to use the
lxc-ps --lxc and kill the processes, hoping we kill the init process
of the container. That's not a big deal until we have thousand of
processes in the container :)

We want to keep the parent of the container init always there, this
process is responsible to manage the container, provide tty, notify
the container changing states and ensure self exclusion (eg. avoid
to launch several containers with the same name).

If this process dies, we consider that as a fatal error and we make
the child process to die too. This patch will just add the prctl to
to send a SIGKILL to the container init process when its parent exits
For the point of view of the pid namespace, when the init process dies
all the processes of the namespace are killed too.

Handle the stop command. The stop command waits for the peer to
disconnect, that means the peer has exited, so it is safe to
return to the user control. By this way, we ensure a stop command
followed by a start or a destroy won't fail with a race condition
because the start command is not yet finised.

Hi,

I have to use the attached patch to allow lxc building in the SUSE build
system. It uses as-needed flag and build thus fails, since -lutil is not

Ship the manpages in the source tarball made by 'make dist', and clean

distributions not to depend on docbook at lxc build time, because the
manpages are already there.

Also update the configure warning message to sound less scary.
