I'm worried about the 4.3 update hosing > those. 4.3 contains several updates, and is (for lack of a better analogy) a quarterly service pack for centos 4. If you fear for production systems, set up a local repo or test on development box. As to things you've installed from source.. it depends on HOW you installed them, and it's something that any update, regardless of minor version changes can interfere with. For instance, today the sendmail update came out and is not part of "THE 4.3" update. If you were already on 4.3 and had installed your own sendmail, it's entirely possible that this update could wreck your day. You should consider providing more detail about how you installed from source, as well as why you didn't use or rebuild an rpm, or use the exclude feature in yum to prevent your own custom packages from potentially being overwritten. -- "They that can give up essential liberty to obtain a little temporary safety deserve neither liberty nor safety'' Benjamin Franklin 1775
