And this can be the case ... they will roll back security items, but there will be some new functionality that is not rolled back. If you really need some new function, then yes, a rebuild is in order. That entails all the things I outlined above though ... figuring out "what else" you need to build first to use as a "BuildRequires", figure out what you have to build after because they depend on the built Share libraries of the package (or one they depend on one of your Newer BuildRequires that you needed). Then you need to set up a method to track all the "out of band" packages that you are adding so you keep them up2date. This can sometimes just be the package in question ... but sometimes it can be a whole bunch of other packages too ... for example, if you built a newer openssl, you would also need to rebuild all of these afterwards (which build against openssl): [hughesjr@localhost SRPMS]$ for srpms in $(ls *.src.rpm); do is_openssl=$(rpm -qp --requires $srpms | grep openssl); if [ "$is_openssl" != "" ]; then echo $srpms; fi; done authd-1.4.3-14.src.rpm autofs-5.0.1-0.rc2.163.el5.src.rpm bind-9.3.6-20.P1.el5.src.rpm bind97-9.7.0-6.P2.el5_7.4.src.rpm certmonger-0.50-3.el5.src.rpm clustermon-0.12.1-7.el5.centos.src.rpm conga-0.12.2-51.el5.centos.src.rpm crypto-utils-2.3-2.el5.src.rpm curl-7.15.5-15.el5.src.rpm cyrus-imapd-2.3.7-12.el5_7.2.src.rpm cyrus-sasl-2.1.22-5.el5_4.3.src.rpm desktop-printing-0.19-20.2.el5.src.rpm distcache-1.4.5-14.1.src.rpm dovecot-1.0.7-7.el5_7.1.src.rpm ecryptfs-utils-75-8.el5.src.rpm elinks-0.11.1-6.el5_4.1.src.rpm epic-2.4-1.src.rpm evolution-connector-2.12.3-11.el5.src.rpm evolution-data-server-1.12.3-18.el5.src.rpm exim-4.63-10.el5.src.rpm fetchmail-6.3.6-4.el5.src.rpm fipscheck-1.2.0-1.el5.src.rpm freeradius-1.1.3-1.6.el5.src.rpm freeradius2-2.1.12-3.el5.src.rpm gftp-2.0.18-3.2.2.src.rpm gnome-vfs2-2.16.2-8.el5.src.rpm hplip-1.6.7-6.el5_6.1.src.rpm hplip3-3.9.8-11.el5_6.1.src.rpm htdig-3.2.0b6-11.el5.src.rpm httpd-2.2.3-63.el5.centos.src.rpm ipsec-tools-0.6.5-14.el5_5.5.src.rpm iscsi-initiator-utils-6.2.0.872-13.el5.src.rpm isns-utils-0.93-1.0.el5.src.rpm java-1.6.0-openjdk-1.6.0.0-1.24.1.10.4.el5.src.rpm kdelibs-3.5.4-26.el5.centos.1.src.rpm kdenetwork-3.5.4-13.el5_6.1.src.rpm libc-client-2004g-2.2.1.src.rpm libdbi-drivers-0.8.1a-1.2.2.src.rpm libgnomeprint22-2.12.1-10.el5.src.rpm libwvstreams-4.2.2-2.1.src.rpm lynx-2.8.5-28.1.el5_2.1.src.rpm m2crypto-0.16-8.el5.src.rpm mod_authz_ldap-0.26-11.el5.src.rpm mutt-1.4.2.2-3.0.2.el5.src.rpm mysql-5.0.77-4.el5_6.6.src.rpm neon-0.25.5-10.el5_4.1.src.rpm net-snmp-5.3.2.2-17.el5.src.rpm NetworkManager-0.7.0-13.el5.src.rpm nmap-4.11-2.src.rpm nss_ldap-253-49.el5.src.rpm ntp-4.2.2p1-15.el5.centos.1.src.rpm openCryptoki-2.2.4-25.el5.src.rpm openhpi-2.14.0-5.el5.src.rpm OpenIPMI-2.0.16-12.el5.src.rpm openldap-2.3.43-25.el5.src.rpm openldap24-libs-2.4.23-5.el5.src.rpm openssh-4.3p2-82.el5.src.rpm pam_ccreds-3-5.src.rpm perl-Crypt-SSLeay-0.51-11.el5.src.rpm perl-Net-SSLeay-1.30-4.fc6.src.rpm php-5.1.6-32.el5.src.rpm php53-5.3.3-5.el5.src.rpm postfix-2.3.3-2.3.el5_6.src.rpm postgresql-8.1.23-1.el5_7.3.src.rpm postgresql84-8.4.9-1.el5_7.1.src.rpm postgresql-odbc64-09.00.0200-1.el5.src.rpm pwlib-1.10.1-7.0.1.el5.src.rpm pyOpenSSL-0.6-2.el5.src.rpm python-2.4.3-46.el5.src.rpm python-ldap-2.2.0-2.1.src.rpm qspice-0.3.0-54.el5_5.2.src.rpm quota-3.13-5.el5.src.rpm rdesktop-1.6.0-7.src.rpm ruby-1.8.5-24.el5.src.rpm samba-3.0.33-3.37.el5.src.rpm samba3x-3.5.10-0.107.el5.src.rpm sblim-1-49.el5.src.rpm scribus-1.3.3.2-3.el5.src.rpm sendmail-8.13.8-8.1.el5_7.src.rpm slrn-0.9.8.1pl1-1.2.2.src.rpm spamassassin-3.3.1-2.el5.src.rpm spice-client-0.8.1-6.el5.src.rpm squid-2.6.STABLE21-6.el5.src.rpm stunnel-4.15-2.el5.1.src.rpm tcpdump-3.9.4-15.el5.src.rpm tn5250-0.17.3-6.src.rpm tog-pegasus-2.11.0-3.el5.src.rpm tpm-tools-1.3.1-1.el5.src.rpm trousers-0.3.1-4.el5.src.rpm vsftpd-2.0.5-24.el5.src.rpm w3m-0.5.1-18.el5.src.rpm wget-1.11.4-2.el5_4.1.src.rpm wireshark-1.0.15-1.el5_6.4.src.rpm wpa_supplicant-0.5.10-9.el5.src.rpm wvdial-1.54.0-5.2.2.1.src.rpm x3270-3.3.4p7-3.el5.4.src.rpm xchat-2.6.6-8.el5.src.rpm xmlsec1-1.2.9-8.1.2.src.rpm So, this can be very challenging.
