CentOS - Mar 2005 - Centos 4 vs Centos 3.4

I have a pile of rack servers to upgrade.  Most are running RH 7.3 or
RH9.  Over the last 4-6 months, I''ve upgraded a few servers to CentOS
(now running 3.4) and have been quite happy with the results.  All the
familiar RH creature comforts, files are where you expect, configuration
is familiar, etc.  So before I take the plunge and start rolling things
out, is there any compelling reason to entertain using Centos 4
instead?  My understanding is that it''s basically the same except for
the 2.6 kernel and updated support packages required for the newer kernel.

The reason I ask is that a number of the machines are dual opteron boxes
so it would be nice to get some of the 64-bit fixins in the 2.6 kernels
that haven''t yet (or may never be) been backported to the 2.4 kernels.

Any suggestions would be greatly appreciated.

Cheers,

Chris

It also has a lot of updated packages, including stuff you might
care about, such as a newer MySQL and supported Subversion
packages, and other stuff you probably don''t care about such as
GNOME 2.8.  It also has SELinux built into the kernel, which might
be useful for you or might not be.

The release notes are now available as
<http://mirror.centos.org/centos/4/os/i386/RELEASE-NOTES-en.html>.
You should take a look at them and see whether you think you''d
gain anything.

Right now, I''m not planning to touch my servers currently running
RHEL 3 or CentOS 3.  I will be evaluating CentOS 4 for workstation
use, but I already know that enough things have changed for me to
have to spend some time redoing my kickstart installer support
scripts and update various configuration files.  I expect I''ll
inflict CentOS 4 on myself to figure out a lot of the issues, then
roll it out more generally in a couple of months.
