[CentOS] patching from different directory

Well, yes, if you run "diff" passing absolute pathnames then (I
believe) it will create a path with absolute pathnames... (It might
not, considering that this is not very useful. GNU tar is an example
of utility which transforms absolute into relative paths since
relative is more useful than relative, although I don't believe diff
does the same, the same logic would apply to it as well.)

However, I don't really see the usefulness of that since that would
restrict you to patching on the same absolute path where you created
the diff...

The purpose of "patch" is for others to be able to apply the same
changes to their codebases, which can be located anywhere in the
directory tree and not necessarily in the same path where you did it.

What exactly is the big problem of changing directories before you
apply the patch?
