Well, right now I don't use them during restore to simplify restart procedure 
and make it more clear for reviewers. In OpenVZ we are doing all restart 
procedure with root's privileges and relying on fact that all such IDs will 
be the same during restart (as we are restarting a container and its file 
system will be the same during restart).
