Scientific Linux 7.0 x86_64 BETA 3 - Aug 19, 2014 == Information == Fermilab's intention is to continue the development and support of Scientific Linux and refine its focus as an operating system for scientific computing. Today we are announcing a beta release of Scientific Linux 7. We continue to develop a stable process for generating and distributing Scientific Linux, with the intent that Scientific Linux remains the same high quality operating system the community has come to expect. Please do not install Pre-Release software in your production environment. CAUTION: THIS IS FOR TESTING PURPOSES ONLY. Please review the SL release notes at: http://ftp.scientificlinux.org/linux/scientific/7rolling/x86_64/os/sl-release-notes.html The Upstream release notes are at: https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/index.html You can find the release at: http://ftp.scientificlinux.org/linux/scientific/7rolling/ NOTE: The 'everything' dvd image requires a Dual-Layer (DL) compatible drive for both burning and booting off of. The livecd-iso-to-disk utility is able to convert this to USB successfully. Alternatively you can utilize the dd command to write the raw image to a USB device. http://ftp.scientificlinux.org/linux/scientific/7rolling/x86_64/os/sl-release-notes.html#_how_to_make_a_bootable_usb_installer Send comments/issues/test reports to: [log in to unmask] == CHANGES SINCE OUR LAST UPDATE == * sl-logos ** Artwork now correctly sized for large KDE desktops *** Thanks Urs Beyerle * kernel/grub2/shim ** These RPMs are a second step towards our Secure Boot implementation. ** shim-unsigned now features the fnal-sl.cer for building shim ** kernel modules are correctly signed by a FNAL cert ** kernel now features a driver update and kpatch public key *** this does not mean Scientific Linux is committing to producing kpatch kernel updates at this time. ** We do not yet have the full stack signed, so for this BETA, you will have to use mokutil to load the SL key .Example Command mokutil --import http://ftp.scientificlinux.org/linux/scientific/7rolling/x86_64/os/SECURE-BOOT-KEY-fnal-sl.der * After release, this step should not be required on any system. NOTE: The kernels in sl7-security have not been updated with secure boot compatibility. == THINGS NOT YET INCLUDED == * OpenAFS ** Stephan Wiesand has offered to build OpenAFS packages for SL7 *** He has a proposal on scientific-linux-devel for a possible packaging setup. Interested parties should provide feedback. * yum-conf-epel ** EPEL is still in BETA and as such we are waiting until things solidify more in that area before loading the repository config information. * Secure Boot ** Scientific Linux has joined the UEFI forum with the intent of providing valid secure boot images. ** This is partially implemented. == REMAINING QUESTIONS == * default tuning ** The current default tuning is the upstream provided 'balanced' from tuned. This profile tries to provide even performance for any workload. Alternatively we could set the profile to one optimized for IO intensive workloads. However, it is less power efficient and less sensitive to latency. == In Conclusion == Please keep the feedback coming! For organization sake, I'll ask that package/feature questions be put into their own email thread. // vim: set syntax=asciidoc:
