Not entirely true -- on hibernate, we do a grub bootonce to force you
back into the same kernel you're already booted into.  The initrd then
as one of its first steps looks at the swap partition (... which in the
Fedora case, is specified as part of the initramfs with support for an
override in /proc/cmdline) and if its a swsusp partition, we resume from it.

Unless someone added it when I wasn't looking, no one has added the
support to dracut for the resume bits
