This patch forces container's init process, to become a session leader, that is its session ID is made the same as its process ID. That might seem unnecessary in general, but if we want to checkpoint a container with CRIU, which is needed for container migration, we must ensure that the SID of each process inside the container points to a process that lives in the same PID namespace as the container. Therefore, we force that the session leader is the init. Signed-off-by: Katerina Koukiou <k.koukiou@gmail.com>
LibVirt : simple API for virtualization
Libvirt is a C toolkit to interact with the virtualization capabilities
of recent versions of Linux (and other OSes). It is free software
available under the GNU Lesser General Public License. Virtualization of
the Linux Operating System means the ability to run multiple instances of
Operating Systems concurrently on a single hardware system where the basic
resources are driven by a Linux instance. The library aim at providing
long term stable C API initially for the Xen paravirtualization but
should be able to integrate other virtualization mechanisms if needed.
