I have Centos 4.2 and I run yum update periodically and manually when security patches are released, etc. Today I saw the sendmail security update and although I don't use sendmail (I use Postfix) I ran "yum update" and got a huge list of 93 packages to update. I presume this is to upgrade to 4.3. As this is a production server I'm nervous about doing an update that big.
Is there a way to not go to 4.3, or should I just go on and load it? I have a few packages I loaded from source, all related to my mail system (dcc, razor, amavisd-new, spamassassin). I'm worried about the 4.3 update hosing those.
Thanks, Scott

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.

At the same time, the /4/ tree is all that gets updates, the 4.2 tree will be moved to the vault, and no more updates will be applied to it from this point.
Please read the FAQ concerning update sets and the major versions ... The Release is CentOS-4 ... 4.3 just means the 3rd update set for CentOS-4 is applied.

You can always download updates individually via ftp.
There IS always a risk with these bigger upgrades. The upgrade to 4.2 brought a bug in the dmraid(?) package that broke my home Linux server. It took help on this site to finally find the problem, which was in the upstream provider's version.
