Thanks for that useful page.

| The other main reason for swap is the one the OP asked about - hibernation.

You don't mention that on your page.  Should you?

Do you meand "you can't hibernate to a swap file"?  Is that
restriction documented somewhere (I haven't looked very hard)?

If you really mean that the system cannot swap to a swap file, is that
documented somewhere?  The swapon(8) awkwardly kind of says that a
file can be used.  mkswap(8) talks about how to initialize a swap file.
