mmmm thinker better... to avoid confusion, prefix filenames can be 
better otherwise will have:

(This also applies for usr-share and lib-modules)

filenames: root_image.fs.sfs
aitab: root_image
fstab /dev/mapper/archiso_root_image

Maybe much better is (what your get is what you see)

filenames: archiso_root_image.fs.sfs
aitab: archiso_root_image
fstab: /dev/mapper/archiso_root_image

Other solution, but can be confusing, is just assing the name 
/dev/mapper/archiso_root_image to "root-image".
