If there's not enough storage available (I'm also thinking of the file
allocator Oliver wants), freeing some memory may get you in a position
No, I do want a dedicated partition. 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?
