But this means that in manjaro you have to wait at least 10 seconds, right? Or are there cases when dhclient is not needed?

Does it make sense to reduce both loops to 5 iterations each, so that Manjaro users won't have to wait that long? (and it would still remain up to 10 seconds for Ubuntu users)

Since this is the same command we have above, I suggest:

  1. renaming this function to ensure_container_network()
  2. create a small check_container_network() function containing the lxc query command
