Nothing changed with respect to how reload operates on Red Hat systems. 
However I seem to recall some issue with mschap after the server was 
HUP'ed to reload the config in some versions of FreeRADIUS I don't 
remember the details of that issue, it's probably in the list archive. 
Maybe someone else remembers better than I.

However, if you use a backend data store (i.e. sql or ldap) to store 
your user data you won't have to reload your configs, just a suggestion.
