Another option is to tweak swapctl so that if you give it -A so
that it reads fstab and adds all marked-as-swap entries, and it
doesn't find any swap entries in fstab, swapctl could complain?

That way you would get the warning when /etc/rc is run, not at
the moment when you run out of memory (at which time producing an
error message can be messy).
