Hm... The new error is because criu tries to PTRACE_SEIZE the init to do the
--restore-sibling restore and can't do it since strace is already there.

Can you (for experiment only) patch out the --restore-sibling option from the
code that calls criu? Or (!) call criu restore manually on the existing images
with all the options being "correct" by yet again w/o the --restore-sibling?
