Hi,
I need to upgrade a system running 4.1 to 4.2, but before I do I want to list
out all the packages that will be updated/installed/removed. I can run up2date
-l to get a list of updates but does that show packages that need to be
installed and removed as well or just the updates?
Second, how would I go about upgrading 4.1 to 4.2 instead of 4.8 (i.e. latest
update).
Unfortunately I don't have access to centos 4.x at the moment.and googling
just centos 4.1 to 4.2 is not bringing up relevant information.
Thanks
Sheraz

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....

It doesn't help to upgrade from a version which is four and a half years old to a version which is four years old. Both have real security issues, both had bug fixes to several of the applications running there. Ralph

Point your system to that repository then run the update.

Your system would be only slightly less vulnerable, and a risk. If the system is isolated from the internet, you MIGHT be safe. But if it touches the wild wild west of the online world, you are just another hacker target just waiting to be found.
