I am not sure if this is a bug in NetworkManager or i fits the right place to ask but here goes:
I recently migrated to arch and took my 16.04 containers with me. This worked like a charm.
However, after I enabled lxc-auto.service (& lxc.service) i had a considerable increase in boot-time. +20 sec to be exact. Now, as far as i can see this is because they are calling for network-online.target, which is understandable.
So, what happens in Ubuntu that’s different? I dont know of any ways to delay systemd services, but why is it halting the rest of the boot process?
