Going to a filesystem is just hiding the problem. Filesystems can return -ENOSPC. I also want my sytem to reliably hibernate if the filesystem to hold the image happens to be remounted ro or to be undergoing a filesystem check. For full reliability you simply need a reservation. In addition that's the fastest solution, too. A simple linear write to an unfragmented area. The typical system today has three orders of magnitude more disk than ram. Do you really have a sytem you want to hibernate that has less than 2two orders of magnitude more disk than ram?
