It doesn't need to, the backend is a file and you can access arbitrary byte positions. The "RMW behaviour" is what the underlying filesystem automatically provides. Maybe we should just provide different layout variants for cgd. I noticed that cgdconfig uses a cgd_ioctl structure to define a disk that has several unused fields. So it is trivial to provide a configuration option that selects a compatible "crypto block size" with 512 byte disks. -- -- Michael van Elst Internet: mlel...@serpens.de "A potential Snark may lurk in every tree."
