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.
