I have two departments each with cups print server on latest Centos 6 (talking to actual printer via jetdirect ports), dozens of CentOS 6 (fully updated as well) workstations which cups talking to print queue servers via LPD (yes I prefer LPD communication here even though it passes jobs over to CUPS then). And never ever I had CUPS configuration dropped after CUPS update (neither on print queue server, not on workstations). just my $0.02. Thanks.
