I think that conflating "memory-to-disk swap space" with "I can
hibernate my machine" is unacceptable. We need a new partition type
that Anaconda would setup, or a whitelist of laptops with firmwares
that support rapid start (and again, Anaconda to set it up), or use a
temporary file of any sort to store the hibernation data. If my
machine has 8 gigs of memory, I don't want to need 8 gigs plus of swap
to be able to hibernate it, when run away processes can make my
machine unusable for hours if they start hitting that swap.
Elsewhere in this thread Zbyszek suggested a RAM-sized swap partition
for hibernation, plus a filesystem-resident swap file that grows as
needed. If such file could be recreated as a sparse / thin-provisioned
object on boot it would be pretty slick.
