Update On Scientific Linux Troy Dawson HEPIX Spring 2010 April 21, 2010

Witty Comment ● Linux is like a wigwam: no gates, no windows and Apache inside. ● "We all know Linux is great...it does infinite loops in 5 seconds." -- Linus ● ● Type “cat /boot/vmlinuz > /dev/audio” to hear the Voice of God ● Failure is not an option – it comes standard with Vista ● ● $ cat “food in a can” ● cat: can not open food in a can ● "We all know Linux is great...it does infinite loops in 5 seconds." -- Linus ● "We all know Linux is great...it does infinite loops in 5 seconds." -- Linus

Scientific Linux ● Presentation Overview – The last six months – What we are currently working on – What we see in the future – Plenary Discussion

Scientific Linux The Past Six Months ● The following statistics were gathered from ftp.scientificlinux.org log filesftp.scientificlinux.org ● These numbers are the minimum. We know that they are higher. ● These numbers are based on the yum and apt access to the errata ● In 2010 we started counting the machines that download the distro mirrorlists. We do not know the architecture of these machines, so they have been labeled as “noarch” ● We currently have 30 public mirrors, and know of 201 sites mirroring us. These statistics do not represent any of the mirror sites.

Scientific Linux The Past Six Months

● The following charts are based on the number of files, and/or the number of megabytes downloaded from ● Past graphs were from ftp not http ● Networks in the US are not counted ● Networks that might be in several countries, such a.org or.net have been taken out as well. ● This isn't to prove anything, these charts are made just for fun.

Scientific Linux The Past Six Months

● S.L. 5.4 released – November 2009 ● For i386 and x86_64 ● Programs that were added ● Lua ● Firmware: iwlwifi-1000, iwlwifi-5150, rt61pci, rt73usb ● comps.xml was cleaned up to match RedHat's ● KVM was added for x86_64 ● Xfs is in the kernel for x86_64

Scientific Linux The Past Six Months ● S.L. Live 5.4 released – November 2009 ● Web site is at ● For i386 and x86_64 ● CD, DVD, mini-CD ● Changes can be stored persistently on a storage device like an USB key ● can be installed on USB key, or local hard disk ● LiveCD can be mounted over NFS (diskless client)

Scientific Linux The Past Six Months ● Security updates continually released for all supported versions ● Fastbugs updates consistantly released weekly for latest versions of SL4 and SL5. ● Testing used more for errata that might cause problems. ● Rrdtool added... and then removed. ● http: instead of https: is now the preference for although people can use either. ● We had a few power outage problems.

Scientific Linux The Past Six Months ● New Scientific Linux Logo – Tweaked logo to allow it to scale better – Put up many sizes of the logo on the site – Created and put up many sizes of a banner – Created and put up many sizes of a “stamp” – Created Scientific Linux Shops ● These shops are non-commission ● ● ● I did two different shops because they both have their strengths and weaknesses

Scientific Linux What we are currently working on ● Building SL 5.5 – Still in the Beta phase – Still updating anaconda (the installer) – Still need to update the comps.xml – Still need to check our added packages – All the other various things we need to do for a release.

Scientific Linux What we are currently working on ● Newer, faster, better distribution servers – New servers have been burned in – Their configurations are much more secure than the last ones. – We had some networking problems which delayed their deployment. – We then had some power problems that further delayed their deployment. – We are all set to change the alias's to the new servers, but I didn't want to do it right before leaving to Hepix.

Scientific Linux What we are currently working on ● More automated build process – We are setting up Koji (the build environment that Fedora and EPEL use) for building SL6 – We have the hardware setup and working. – We have a Koji Hub setup and working – Currently working on setting up more build nodes as well as a cvs/svn repository – When it is setup, we are hoping that this will allow other collaborators to be able to build for SL6

Scientific Linux What we are currently working on ● Setting up a spacewalk server that possibly will allow us to show the security errata – Still in testing, this may not happen – We want something similar to ● – Maybe it could possibly be a master SL spacewalk server that others could sync from.

Scientific Linux What we are currently working on ● Building SL 6 Pre-Alpha – RedHat released RHEL 6 Alpha April 21, 2010 – We are still recompiling that, the first time – We are still testing out our Koji environment – After we have recompiled everything once, we will then recompile everything again on our new environment... as much as we can. ● In the past, RHEL releases couldn't build on themselves. – Although we will work on getting a Pre-Alpha version of SL6 out, our priority will be to get SL 5.5 released.

Scientific Linux What we see in the future ● Continue to have security updates for SL – This will continue until October 2010 ● Continue to have security updates for all releases of SL 4 until SL 4 goes into legacy mode. ● Due to the delay of RHEL 4.9, we have no date for when we will go into SL 4 legacy mode. ● At that point SL will be moved to obsolete and only SL 4.9 will have security updates. ● Continue to have security updates for all releases of SL 5 ● Continue to have fastbug updates for only the latest release of SL 5

Scientific Linux What we see in the future ● Releasing S.L. 4.9 – Estimate - ?? 2010 ● Releasing S.L. 5.5 – Estimate - June 2010 ● When RHEL 6 comes out, releasing S.L. 6.0 – Estimate - February 2011 ● RHEL 6 beta – April ● RHEL 6 released – late October or November 2010 ● This is a guess. ● Red Hat will not release RHEL 6 untl “it is ready” ● We will not release SL 6 until “it is ready”

Scientific Linux What we see in the future ● Create errata.scientificlinux.org similar to ● This would be on our spacewalk server ● More automation of rpm checking and errata . ● This is progressing. The scripts and programs being written for our spacewalk server are a very large step forward in this direction.

Scientific Linux Plenary Discussion ● This is our chance to get direction from you, the users of Scientific Linux – What is important – What should we change – Discuss time lines and road maps
