Scientific Linux 7.2 x86_64 Release Candidate - Feb 2, 2016

== Information ==

If no critical bugs are reported by Feb 5, 2016 this will become the official release of Scientific Linux 7.2

NOTE: Please review the SL Release Notes along with
The Upstream Vendor's Release Notes:

http://ftp.scientificlinux.org/linux/scientific/7.2/x86_64/release-notes/

https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/index.html

There is a great deal of information within those documents not listed here.

Send comments/issues/test reports to:
SCIENTIFIC-LINUX-DEVEL@LISTSERV.FNAL.GOV

== Media ==
You can find the release media at:
http://ftp.scientificlinux.org/linux/scientific/7.2/x86_64/iso/

Alternatively the livecd-iso-to-disk utility is able to convert
this to USB successfully. A USB device of sufficient size is
required.

Alternatively you can utilize the dd command to write the
raw image to a USB device.

== SL Specific Updates ==
.External Repos
With SL 7.2, yum-conf files pointing to non-base SL (such as EPEL, ELRepo,
SL-Extras, SL-SoftwareCollections, ZFS) have moved to a central location.
Since these repos are not specific to individual releases of SL, the
separate location will allow for easier adding and removing of these resources
for any SL7 system.
To load a resource, such as EPEL:
`yum install yum-conf-repos` followed by `yum install yum-conf-epel`.

.Install Media Updates
The install media now features the yum-fastest-mirror plugin.
The yum-fastest-mirror plugin should locate a quickly responding
mirror for network installs. SL specific yum vars are now expanded
as expected.

.Scientific Linux Contexts
SL 7.2 includes initial support for Scientific Linux Contexts which
should allow for ease of creating local customization for specific
computing needs.
For more information on Scientific Linux Contexts:
http://ftp.scientificlinux.org/linux/scientific/7/contexts/README.html

.OpenAFS
With SL 7.2 OpenAFS has been updated to version 1.6.16 the latest upstream stable.

.Yum behavior update
Backported patch from upstream for yum fs-vars, per BZ#1281593
Now yum vars set in /etc/yum/vars will be checked even in an
alternate yum-root.
Thanks for the bug report Lincoln Bryant!

.IPA customizations
The IPA packages have been customized to remove the upstream links to their support services.

.Build Fixes
The curl and mariadb packages were modified to ensure their unit tests for date validation worked after Oct 2015

== Known Bugs ==
.AMD IOMMU
Some AMD systems may need additional kernel arguments for system stability. See upstream Bugzilla 1265283, 1274527, 1285235



== UEFI Secure Boot ==
The status of UEFI Secure Boot for Scientific Linux is noted in detail at:

http://ftp.scientificlinux.org/linux/scientific/7/x86_64/release-notes/#_about_uefi_secure_boot

Booting SL7 with Secure Boot enabled works but requires a manual step.
This is because the "shim" has not been signed by the UEFI CA.
Instructions are included within the SL7 Release Notes.

The best way to get my attention is over the official lists.
