Issues/thoughts re CentOS-4
by John Newbigin 20 Dec '04

20 Dec '04

This is a list of issues for discussion for CentOS-4. Most of it is based on my experience from building/maintaining CentOS-2 and observing CentOS-3. I have not seen the CentOS-4 beta yet so I don't know if any of this is already done. If these have been discussed on IRC then perhaps someone could produce a shot summary of the outcomes....? * Just call it CentOS-4 not 4.1 etc. Too confusing and serves no real purpose * All modified rpm should use mezzanine or equiv. This makes it easier to track changes, build updates and generate a report on what has changed. * Modified rpm should have .c4.n added to the release - c4 = centos 4. (works well once the 4.1 is dropped) - .n = a number starting at 1. The spec only 0 does not scale if you need to make another spec only change. The changelog will tell you what has changed. * Mission: To stay as close to RedHat as possible Issues: some things need to be modified to support this. For example the cpu/memory restrictions will be removed(like in CentOS-3). Given that we are doing this, should we also lift other artificial constraints like installing on i386? If we start making changes, where do we draw the line? In CentOS-2 I have fixed some small 1 line bugs (mostly packaging issues) but this might be a contentious issue. What about a CentOS+ repo. for enhanced versions? * Issue: should the distro be self hosting? I think as long as the requirements are available from the addon/extras repos. then I don't think this is needed out of the box. Obviously the build environment needs to be well documented and reproducible. * Mission: Remove RedHat trademarks. Issues: should we replace all rh logos/icons or just the ones required by RedHat? I think if the file/words can be replaced then yes, but package names etc. should be left alone. * Issue: yum Don't ever auto-modify yum.conf. Too confusing. Invent a system for selecting/allocating a mirror. Users should always use a 3rd party mirror and not the main caosity mirrors. Issue: every mirror has different paths. We need to clean up all the symlinks and multi versions on the mirrors. (We need someone in change of the mirrors) * Issue: gpg key. This should be installed by default so the user does not have to find & import it. At a minimum it should be in /usr/share/doc/centos-release and work like a RedHat box. * Issue: release QA Before public release, a QA procedure should make sure that there are no obvious problems (like the comps issue of 3.3). * Idea: automatic patch building. It should be possible to build most patches without intervention. I don't know what the current systems in place are but if there were autobuilt unsigned patches available it would allow - testing of patches before they are 'officially' released - checking the progress if a patch Using an automatic system to apply CentOS specific modifications means that in some cases, the CentOS specific changes can also be autoapplied and the package build. Obviously before a package is officially released, someone needs to check that it is correct and works etc. John. -- John Newbigin Computer Systems Officer Faculty of Information and Communication Technologies Swinburne University of Technology Melbourne, Australia http://www.it.swin.edu.au/staff/jnewbigin

3ware 9000 install
by aemadrid＠hyperxmedia.com 20 Dec '04

20 Dec '04

I'm trying to do a fresh install on a new server that has a 3ware 9000 controller. I followed the instructions on the 3ware manual and used a floppy with the drivers for RH WS3 (Update 2) but it doesn't work. After it asks me to load the disk it reads for a while and then it says it did not find any drivers that pertain to this system. I tried loading the 3w9xxx driver unsuccesfully, it does no recognize the drives. Has anybody succesfully installed Centos-3 on a server with a 3ware 9000 controller? How? I have another machine that does not have a raid controller (and I'm installing Centos right now) that I can use to ciompile the drivers or whatever is needed. Thanks in advance, Adrian Madrid ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program.

PHP
by Rob Poe 18 Dec '04

18 Dec '04

Saw on Slashdot there are a few vulnerabilities with PHP. Do these vulnerabilities affect the PHP that's installed? If so, is RedHat going to backport or should I go ahead and grab from source?

Re: [Centos] Centos as a desktop

"TK" == Ted Kaczmarek <tedkaz(a)optonline.net> TK> I don't want to discourage one from using Centos for a TK> workstation, but you may want to at least run TK> dual/triple/quad boot and drive a distro(s) geared for the TK> workstation/desktop as well. If your objective is to just TK> run a work station and are not looking for all the toys, TK> than Centos is for you. If you want to live on the edge, TK> have all the latest and greatest, than leave 10-15 gig on TK> the drive for the latest Fedora release. I personally TK> prefer to live on the edge on my two machines I do most of TK> my work on, it seems to minimize my learning curve going TK> forward, and also helps the community in general, but that TK> is me, and you are you. Hey, it's a *work*station. I need it to work, all the time, as it's my main gateway into all the other machines. I also need to be able to write documents, admin the other systems, duplicate and fix user problems, prototype code and websites, and so on. For play, I have a bunch of other machines in my office (including the damn Beowulf cluster that hasn't been moved yet!), a shiny Powerbook, and my keen Debian development box at home. That said, yes, if you want the very, very latest and greatest, then I guess CentOS 3 isn't your first choice, any more than Red Hat Enterprise Linux WS or AS or Debian stable would be. For edges so sharp their users are anemic, we have distros like Debian unstable, Fedora Core development (is it still Rawhide), Mandrake Cooker, and so forth. For workstations, stable OSs with support and the occasional newer package work pretty well.

list suggestion
by Francois Caen 17 Dec '04

17 Dec '04

Hello, I'm fairly new to CentOS and to this list. I was wondering if the possibility of creating an announce-only list for CentOS had been discussed before? I'm mostly interested in patch releases and official announcements from the distro maintainers. (great job, BTW! :-) Thanks, Francois
