For BZ1206936 [1] we started adding resume= kernel command line by

I would ask the question:
Is resume=/path/to/swap something we really want on server installs
like Fedora Server and Fedora Atomic Host?
It seems *unnecessary*, but I'm not sure I understand what problems it
causes. Could you got into more detail there?
I can't see anyone putting a Server or Atomic Host into hibernation,
though. Does this just direct the kernel where that should go if
hibernation is requested, or does it reserve space or something for
it?
AFAIK it tells the kernel where to look for a hibernation image to
restore from - so it normally points at one of the swap partitions.
If the kernel finds a hibernation image on the specified device then
it will restore that and switch to it otherwise it will just continue
booting as normal.
