Twiki is a perl web application run under apache. It doesn't have its
own uid. It doesn't 'have' to be anywhere in particular but that is
the way it was written and thus has very confusing results when trying
to move it to CentOS 7. Is there some generic approach to fixing this
kind of breakage (that is, to make it work and not confusing, not to
say it was broken as designed)? To function as a backup, it
probably shouldn't default to being in the same directory as the files
it backs up.
