When you go from disabled to permissive, then to enforcing, this is very true,
because then no objects have labels.
The issue with permissive to enforcing, is that people may have been mv-ing
directories around, putting things in the wrong locations (so they have the
correct label for where they are, but wrong relative to the application).
There certainly won't be as many issues as disabled -> permissive, but there are
still enough subtle things that can change an go wrong, that it's worth the
relabel to be sure that your issues going from perm -> enforce are not related to
mislabeling, but perhaps other issues.
