This is correct, but unpractical as it means that you have to have root
privileges.  Alternatively, you can set the LD_LIBRARY_PATH environment
variable to include /home/jerry/usr/lib, but this will only work for the
shells in which this is done.

As long as the name of the .so-file remains the same, there should be no need.

Yes.  Basically, as long as a filename is to the right of all arrows '=>',
everything has worked.
