Run weave on top of early-docker just as flannel

[Adam Stankiewicz]

Hey,

I thought it might be a good idea to run weave on top of early-docker, just as flannel does:
https://coreos.com/flannel/docs/latest/flannel-config.html

Here's its service file from coreos:

[Unit]
Description=Network fabric for containers
Documentation=https://github.com/coreos/flannel
Requires=early-docker.service
After=etcd.service etcd2.service early-docker.service
Before=early-docker.target

[Service]
Type=notify
Restart=always
RestartSec=5
Environment="TMPDIR=/var/tmp/"
Environment="DOCKER_HOST=unix:///var/run/early-docker.sock"
Environment="FLANNEL_VER=0.5.3"
Environment="ETCD_SSL_DIR=/etc/ssl/etcd"
Environment="FLANNEL_ENV_FILE=/run/flannel/options.env"
