+.LP
+As of 3.2.28, any file in <installroot>/<persistdir>/vars is turned into
+a variable named after the filename (or overrides any of the above varaibles).
+The obvious exception is that you cannot use these variables in the definition
+of persistdir itself.
+
+Note that no warnings/errors are given if the files are unreadable, so creating
+files that only root can read may be confusing for users.
+
+Also note that all new line characters are removed, as a convienience, but no
+other checking is performed on the data. This means it's possible to have bad
+character data in baseurl etc.
