Also, why was this syntax introduced in the first place? Why should the user 
care??

We should only have a single crashkernel option, to enable it - and everything 
else should be figured out by the kernel, automatically.

Any other sub-options just paper over some fragility elsewhere and make the 
feature harder to use, hence more fragile.

Thanks,
