Subject: lxc-init kills all processes with SIGTERM
X-Git-Tag: lxc-0.7.2~21
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6fd1668e7f96c15b8688a0fa955e2c10bbc4785d;p=thirdparty%2Flxc.git

lxc-init kills all processes with SIGTERM

When lxc-init receives a SIGTERM, let's kill all the processes of
the pid namespace with kill -1. So the exit of the container will
happen gracefully with processes death cascade.
