there IS no such thing!
Each process has it's OWN mount tree, including own "root filesystem".
It's called "namespaces". Sure, often they're shared. But that's not a
given.

So read again:
THERE IS NO SUCH THING AS *THE* ROOT FILESYSTEM.

If your code assumes there is then you need to rethink it!

no because a mount point can be mounted in different places, and you
don't know which one to chase.
