(Disclaimer: all below is AFAIK and it might be slightly wrong) On swapon(), a block map of the file / partition is made by the kernel and later I/O to the swap area are not going through the filesystem layer. So FUSE is not involved in the suspend process at the stage of image writing. Have fun, Stefan -- Stefan Seyfried "Any ideas, John?"
