What will be reloaded by freeradius server on received SIGHUP signal?

[work vlpl]

Hello,
I want to know what will be reloaded by freeradius server on received
SIGHUP signal.

I found this message in archives
http://lists.freeradius.org/pipermail/freeradius-users/2010-November/050062.html

Is it still true?

Also I tried rename certificates filepath  in eap to wrong value.
After kill -HUP radiusd not stop. But in debug output radiusd print
this

Ready to process requests
Received HUP signal
HUP - Re-reading configuration files
including configuration file /usr/local/etc/raddb/radiusd.conf
including configuration file /usr/local/etc/raddb/proxy.conf
including configuration file /usr/local/etc/raddb/clients.conf
including files in directory /usr/local/etc/raddb/mods-enabled/
including configuration file /usr/local/etc/raddb/mods-enabled/eap
including configuration file /usr/local/etc/raddb/mods-enabled/detail.log
including configuration file /usr/local/etc/raddb/mods-enabled/ntlm_auth
...

So radiusd report what it reread eap config. That probably means what
radiusd know about changed in eap module.
