Align transform Y axis to -Physics.gravity

Question

I've been trying to align a transform's Y axis to -Physics.gravity vector but can't get it right. I've tried transform.LookAt, Quaternion.LookRotation, but I need something that doesn't need a forward vector. I'm having problems when I try LookAt with the forward and the up vectors being in opposite directions. Any ideas?

Try this:

 var q = Quaternion.FromToRotation(transform.up, -Physics.gravity);
 transform.rotation = q * transform.rotation;
