Yes, although I do not know what these "register" and "status" mean, I
nevr used autofs.

But this doesn't matter. We obviously can't restore this mount without
special processing:

	40 17 0:33 / /proc/sys/fs/binfmt_misc rw,relatime shared:23 - autofs systemd-1 rw,fd=35,pgrp=1,timeout=300,minproto=5,maxproto=5,direct

(in fact I do not understand at all how criu could do this 100% correctly,
 but this doesn't matter).
