It's fine to list both here because "Should-Start" is a loose binding (ie, if the listed service exists, it'll be started first, but otherwise, this one will start without it). Docker-DCO-1.1-Signed-off-by: Andrew Page <admwiggin@gmail.com> (github: tianon)

# Short-Description: Create lightweight, portable, self-sufficient containers.
|
|
# Description:
|
|
# Docker is an open-source project to easily create lightweight, portable,
|
|
# self-sufficient containers from any application. The same container that a
|
|
# developer builds and tests on a laptop can run at scale, in production, on
|
|
# VMs, bare metal, OpenStack clusters, public clouds and more.
