Was not aware of that program? Was already installed on
my system. Following instructions from link, it found 279
of the broken links under /usr and after checking, I went
ahead are removed them.
Doing the run using / instead of /usr it comes up with the
other 29 in various placed. That includes the one I
created for test earlier, but is 28 I'll have to look into
more. Using the symlink to fix the 279 seems good.
