Systemd compares the amount of memory used to the available swap space and does not offer hibernation if there isn't enough. I haven't seen reports that this calculation is not done properly.
I was told years ago that there's no way userspace can reliably know, and even if we activated a dedicated bigger-than-memory sized swap partition immediately before hibernate started it could still fail. maybe things have improved since then, or maybe it wasn't accurate information. dunno.
Sure, this is correct. But the chances of that happening are fairly low, so among all the problems we have, this seems like a relatively minor issue.
