Why?
First of all
if [ -n ] ; then
echo true
else
echo false
fi
does return what? Yes, it returns "true".
So, if no $old_version is set as on new install, then the
first test is true and the second is NOT executed.
If $old_version is set, the comparison works correct.
So, can you *produce* this bug or are you only reading code without
checking?
