In my case i masked the service because like i said, inside the lxc container there is no networking to do, it's done on the host (proxmox). Note that disabling the service in my case was not enough since it could be invoked by other services, and then you would have to wait again.
See this for further info and maybe arguments why you shouldn't do it.
Any way to speed this up? On my system in every boot it waits for network for 30s.
