Can't kerneld be made to check if it is a symlink and then query the
destination? Sure...

Also this is not really a solution for something you load on an off with a
module. I'm talking about being able to easily add, remove, or change,
drives and partitions with little hassle. This would be especialy useful in
RAID scenarios. Infact I think they do something like this already but it
is specific to the RAID.
