If I understand what the problem is and the proposed solution:

DONT DO THAT.

The mount program needs certain libs - if you put them on another partition then it won't work (you need mount to get the other partition mounted).

If you need more libs put the new ones in another directory and use LD_LIBRARY_PATH to specifiy further directories to be searched for libraries. You can also specify this in a config file in /etc.
