Most initramfs systems will parse the root= line of your kernel command 
line and use it to remount root. The kernel seems like the best place to 
establish this, since the various initramfs solutions will implement the 
same format just to support parsing the kernel command line correctly. I 
mean, maybe that's not enough to justify putting it in the kernel, but 
that's why I see the kernel as the appropriate place to implement this 
feature.
