I remember vaguely that HUPing was at least once used to re-read updated
CRLs and probably also re-reading the list/directory of trusted client-CA
certificates for all the EAP-(T)TLS/PEAP stuff.

I an email recently send to freeradius-users you recommended to simply
restart the daemon for this since HUPing does not work for this purpose anymore.
