Comment) The .x is just a baseline at the time but yum/centos doesn't have the concept of .x minor versions as such (to my understanding) but rather it is a baseline change with possibly some new/changed aspects (such as introduction of postgres84 in the 5.5 case or ext4 tech preview in 5.2 or something). As such trying to stay on an old .x will possibly result in missed security patches and so on as those parts of the mirrors potentially might not get updated. Rather than Centos 4.1, 4.2, 4.3, 3.1,3.2,5.1 and so on from a package mangement (read yum) perspective it is pretty much centos 3, 4, 5 and soon (ish) 6. This would be why in the centos-announce mailing list, as an example, errata are not referred to as centos 4.3, centos 5.1 and so on but there just centos 3, centos 4 or centos 5. Question) 4.2 was a long... long... time ago - why not move to the current centos 4 baseline of 4.8 if you are unable to upgrade to the next major centos release (5)? BTW someone please correct me on the comment if I am mistaken.... but I recall a discussion similar to this last week over complaints of EPEL tracking rhel and needing 5.5 for some packages but centos being at a 5.4 baseline still....
