This is potentially a very dumb question; please bear with me.
I have an older thinkpad currently running OpenBSD 7.6. I have
recently added more RAM to the thinkpad, so the swap partition is
smaller than available RAM.
Is there a way I can prevent OBSD from entering hibernation state?
Reading apmd(8), I didn't see anything obvious, but I got the false
hope that if any of the /etc/apm/{hibernate,standby,suspend} were to
exit with non-0 exit code, maybe the respective state transition would
be aborted. I tried zzz(8) with /etc/apm/suspend with only false(1),
but that did not prevent zzz(8) suspending.

In the dark, I must have fat-fingered and hit the Fn+suspend-to-disk
combination. I have never before attempted hibernation so I had no
idea what the process entails. The system seemed to go through
similar steps as it does during suspend, but after blanking the screen
the power button light continued flashing, and seemed to just continue
forever. I assume(d) b/c the swap size is too small for current
memory, the process was stuck in a loop. I eventually powered-off and
restarted, and never having experienced hibernation cycle, I learned
OBSD tried to unpack (I assume) an incomplete image, which after an
interesting graphics display dropped me into ddb :-)
I am hoping there is a simple way to prevent hibernation from even
being attempted, at least, until I resize my swap partition.
I assume the hibernate path is much too complicated and a simple if
(swap_size < mem) check to abort hibernation is infeasible.
