"We will not add code to systemd that works often but not always" you 
need to explain this a bit further since we might have different 
perception on this since from my perception such code has been added to 
systemd in more then one occasion anyway I was not advocating for the 
use/inclusion of CRIU but something built in.

We should be able to support non live migration out of the box if live 
migration is a pandora's box or are you opposed to that as well?
