[Coco] low-level format of CF on Super IDE (i.e. where do the disk images go?)

So, let's say I want to start with a blank CF and prepare it for
use with the Super IDE controller running HDB-DOS. What is the
sector-by-sector layout I would use for laying-down RSDOS diskette
images and finally the RBF image for use by OS-9?
Is space always reserved at the beginning for 256 diskette images?
Are the images presumed to be a certain number of tracks/sides?
If not, is there anything written on the CF to indicate the different
size or number of images?
My intuition suggests that given an acceptable number and size of
diskette images, it would be as simple as this (in Linux or similar):
cat disk1.dsk > cfimage.bin
cat disk2.dsk >> cfimage.bin
...
cat disk255.dsk >> cfimage.bin
cat rbfimage.os9 >> cfimage.bin
dd if=cfimage.bin of=/dev/sdb # where /dev/sdb represents the CF device
Am I on the right track?
