 I see three possible solutions.
 
 Drop setroot calls in MD code and adjust documentation (cpu_rootconf(9)).
 cpu_rootconf is then only a hook that lets MD code set the variables
 booted_device, booted_partition, booted_startblk, booted_blks.
 
 Drop MI rootconf() and push detection of wedge 'aliases' into setroot().
 Adjust setroot() signature to also pass in booted_startblk and booted_blks.
 
 Change setroot() to only remember the root specification and make rootconf()
 do the actual work with printing and RB_ASKNAME dance.
