Blivet code has swap = mem + swap when hibernation=True, so for anything with less than 64GB RAM swap is effectively 2x RAM. [1] However, blivet has hibernation=False so we get 1x which sometimes isn't enough. Further, anaconda doesn't set resume= boot parameter. So we're not currently configured to support suspend to disk as far as I can tell.
