Comment 22 for bug 1509414

I was able to For stage two, at least with systemd, I changed /lib/systemd/system/lxd-startup.service to:

[Unit]
Description=Container hypervisor based on LXC - boot time check
After=cgmanager.service lxd-unix.socket
Requires=cgmanager.service lxd-unix.socket

[Service]
Type=oneshot
ExecStart=/usr/bin/lxd activateifneeded
TimeoutSec=30s

[Install]
WantedBy=multi-user.target

while removing the files

    /etc/systemd/system/multi-user.target.wants/lxc-net.service
    /etc/systemd/system/multi-user.target.wants/lxc.service

(i.e. in packaging we would remove

[Install]
WantedBy=multi-user.target

from /lib/systemd/system/lxc{,-net}.service)

Now when the system comes up, lxcbr0 is not there. When I do 'lxc list', it comes up.

A user who wants to use non-lxd lxc can do

sudo systemctl add-wants multi-user.target lxc.service

to make lxc and lxc-net start back up at boot.

The lxd-startup.service also still works, since it works by activating lxd if the database shows containers need to be started.
