Well ... you could try the in-kernel hibernate (which I think is what
'systemctl hibernate' does), though you'd lose the nifty features of
µswsusp.

In the end, though, I'll probably have to revert all those IS_SWAPFILE
checks (at least if CONFIG_HIBERNATION=y) since it's not fair to force
you to totally reconfigure your hibernation setup.
