Hibernate usually copies active ram to a pre-allocated hibernation
file

https://doc.opensuse.org/documentation/leap/reference/html/
book.opensuse.reference/cha.power-mgmt.html says Leap hibernates to swap if
swap is sufficiently big. A hibernation file is not mentioned.

Of course, if swap is in heavy use already a dedicated hibernation file with
the size of used RAM (minus gains from compression) is needed.

https://en.opensuse.org/SDB:Suspend_to_disk is out-dated (last tested on
openSUSE 11.3) and nothing with "s2disk" in the filename exists in /var or /
etc on my Leap 15.0 laptop.

Any pointers how to make sure hibernation is always possible? If there no
longer is the possibility of a separate hibernation file (that cannot be
claimed for swap space) how would one limit swap usage to swapsize-ramsize?

Joachim
