Subject: [Buildroot] [PATCH 1/9] dumb-init: new package
Date: Wed, 20 Sep 2017 04:02:02 +0100	[thread overview]
Message-ID: <20170920030210.19446-2-christian@paral.in> (raw)
In-Reply-To: <20170920030210.19446-1-christian@paral.in>

dumb-init is a minimal init process to act as PID 1 for containers.

dumb-init can be used to satisfy docker-engine's docker-init binary
requirement.

In many cases docker-init backing processes like dumb-init must be static, as
they are executed inside a container in an unknown environment. This
patch includes an option to specifically compile dumb-init statically, even if
the system is compiled dynamically.
