Scientific Linux 6.8 RC 1 i386/x86_64 June 30, 2016
These are notes of the "Release Candidate" release for Scientific Linux 6.8 .
--------------------------------------------------------------------------
THIS IS NOT FOR PRODUCTION.
This is for testing. Please report back any issues to
[log in to unmask] .
There should be no expectation that a "yum" upgrade to SL 6.8 will work.
A new install is the recommended method to move from
"sl6rolling" and the released SL 6.8.

Packages Changed by Scientific Linux
---------------------------------------------------------------------------
Packages modified by Scientific Linux should contain 'sl' within their
release string.
Packages can be changed for a few reasons - removing trademarks, fixing
errors, providing different behavior, or fixing build issues. Each of the
changed packages below lists is reason for its change along with some
historical information.

---------------------------------------------------------------------------
PACKAGES CHANGED FOR BUILDING REASONS
Some packages would not build in our build environment. We changed these
packages in order for them, or other packages, to build. The changes are
minimal and are associated with a bug filed upstream to hopefully reduce
this list over time. The final packages have been compared to freely
available ones and are not significantly different.
To distinguish these packages we typically put 0.sl6 at the end of the
release number.
---------------------------------------------------------------------------
epydoc
To fix a build error with python-nss a patch was added (bz#578920)
This change went into effect with SL 6.0 and was fixed by upstream in
6.1 . For some features texlive-dvips and texlive-latex are required,
but not listed in the SPEC file. (bz#522249)
This change went into effect with SL 6.0 and continues in this
release.
mod_auth_kerb
We Changed "--with-krb5=/usr/kerberos" to "--with-krb5=/usr" because
the krb location changed in SL6. (bz#661777)
This change went into effect with SL 6.0 and ended with SL 6.3
opal
opal needed a bug fix patch in order for ekiga to build. The
opal-3.6.6-buildopts.patch was missing one line for it to work
properly.
(bz#661769)
This change went into effect with SL 6.0 and continues in this
release.
pilot-link
When "autoreconf -is" is called this causes libtool to run from
/usr/bin/libtool which is version 2.2.6b but the source ships its own
libtool in
pilot-link-0.12.4/libtool which is version 2.2.6 and called from the
make files. This version mix does not work. (bz#663632)
This change went into effect with SL 6.0 and continues in this
release.
rome
TUV 6 provides jdom-1.1.1 and not jdom-1.0 so we changed it to 1.1.1
(bz#665537)
This change went into effect with SL 6.0 and continues in this
release.
qpid-cpp
The SPEC file wrongly mandates TUV be listed as the vendor (bz#785919)
This change went into effect with SL 6.2 and ended in SL 6.3
qpid-qmf
The SPEC file wrongly mandates TUV be listed as the vendor (bz#785921)
This change went into effect with SL 6.2 and ended in SL 6.3
compat-openmpi
One of the post-build tests was not functioning correctly with build
environments containing nfs mounts. Patched with corresponding test
from current version. (bz#1340549)
----------------------------------------------------------------------------
CHANGES TO COMPS.XML
The comps.xml file determines what packages are in groups. This determines
what packages get installed automatically when you select a group during
install, or when you use yum groupinstall.
---------------------------------------------------------------------------
We have made the following changes to comps.
We merged all of the comps.xml files from The Upstream Vendor into one
file for each arch. If a group was in any of TUV comps.xml files, for that
arch, then it was included in our comps.xml file. If a group was default
for either of TUV comps.xml, then is was made default in our comps.xml
file. If a package was in a group for either of TUV comps.xml files, then
it was put in that group in our comps.xml file.
Added the following groups:
icewm
misc-sl
openafs-client
repos
spins

---------------------------------------------------------------------------
ADDED compared to Enterprise 6
---------------------------------------------------------------------------
PACKAGES ADDED
---------------------------------------------------------------------------
We have added several packages to Scientific Linux that are not found
anywhere on the Enterprise releases. These have been added for various
reasons which are noted below.
icewm
This was added with SL 6.0 and continues in this release.
Summary : Fast and small X11 window manager
Added because we needed a lightweight modern window manager. There are
some machines that just don't have much CPU and/or memory, and both
KDE and GNOME can really slow these machines down.
This is not installed by default.
icewm
icewm-l10n
imlib - for dependencies
gtk+ - for dependencies
glib - for dependencies
OpenAFS
This was added with SL 6.0 and continues in this release.
Summary : OpenAFS distributed filesystem
Added because many educational and research centers around the world
use AFS as some type of central file system.
This is not installed by default.
openafs
openafs-authlibs
openafs-client
openafs-compat
openafs-firstboot
openafs-kernel-source
openafs-kpasswd
openafs-krb5
openafs-plumbing-tools
openafs-server

This was added with SL 6.0 and moved into 'sl-adons' in 6.4.
Summary : Scientific Linux Spin Creation
Tools to create Scientific Linux "Spins" or "Sites"
This was not installed by default.
revisor
revisor-cli
revisor-gui
revisor-isolinux
revisor-rebrand
revisor-reuseinstaller
revisor-unity-scripts
sl-revisor-configs
livecd-tools
liveusb-creator
yum-autoupdate
This was added with SL 6.0 and continues in this release.
Summary : Automatically update your machine daily via yum.
Added for those users who want their system automatically updated
without having to worry about doing it by hand.
This is installed by default.
yum-autoupdate
abattis-cantarell-fonts
This was added with SL 6.1 and continues in this release.
Summary : Cantarell, a Humanist sans-serif font family
Added because our new graphical theme uses this font.
This is not installed by default.
abattis-cantarell-fonts
glusterfs-server
These became dependancies and were added as of SL 6.8.
Summary : Cluster file system
The following packages were added in support of glusterfs-server.
These are not installed by default. glusterfs-server is offered as
x86_64 only.
nfs-ganesha
nfs-ganesha-gluster
userspace-rcu - for dependencies
userspace-rcu-devel - for dependencies
pyxattr - for dependencies
alpine
Alpine had been added in the past but was removed from 6.8 as it is
in EPEL.
External Repositories for yum
This was added with SL 6.0 and continues in this release.
Summary : Various External Yum Repositories
These are not supported by Scientific Linux but are here for your
convenience.
This is not installed by default.
adobe-release / yum-conf-adobe
atrpms-repo / yum-conf-atrpms
elrepo-release / yum-conf-elrepo
epel-release / yum-conf-epel
rpmforge-release / yum-conf-rpmforge
rpmfusion-free-release / yum-conf-rpmfusion
---------------------------------------------------------------------------
Tweak RPMs ADDED
---------------------------------------------------------------------------
One of the goals of Scientific Linux is to be as close to the original
vendor release of Enterprise Linux. But there are several things that
people want to change, for one reason or another. In order to have both
worlds we have created these tweak rpm's, more commonly known as SL rpm's.
These rpm's can be added or removed to add or remove a feature. It is up
the individual user to determine if they want a particular feature or not.
None of these packages are installed by default unless it is noted that
they are.
SL_desktop_tweaks
This adds a terminal icon to the kicker panel for GNOME. It also adds
the "add/remove programs" menu item to KDE.
Installed by default for the GNOME and KDE desktop groups.
This was added with SL 6.0 and continues in this release.
Who Needs This?
Pretty much any previous desktop user of linux. It's not a necessity,
and the icons can be added manually, but it's much nicer to just have
them there from the start.
SL_enable_serialconsole
This script makes all the changes necessary to send console output to
both the serial port and the screen. This also creates a login prompt
on the serial port and allows users to login at this prompt.
This was added with SL 6.0 and continues in this release.
Who Needs This?
Headless servers that want to redirect their output through their
serial console during bootup, and also plan on logging in on
those consoles.
Note: It is usually best to install this package after an install. You can
either do this by hand, or in the %post section of a kickstart file. This
is because the grub file and bootloader aren't created during an install,
until after all the packages are installed.
There are 4 packages, which correspond to a serial port speed
SL_enable_serialconsole
SL_enable_serialconsole-96 (9600 baud)
SL_enable_serialconsole-192 (19200 baud)
SL_enable_serialconsole-384 (38400 baud)
SL_enable_serialconsole-1152 (115200 baud)
SL_no_colorls
Turns off automatic colors in ls.
This was added with SL 6.0 and continues in this release.
Who Needs This?
People who don't like the colorized ls or whose terminals can't read
the escape sequences.
SL_password_for_singleuser
Changes /etc/sysconfit/init to require the root password for single
user mode.
This was added with SL 6.0 and continues in this release.
Who Needs This?
In our opinion, everyone needs this. We're quite surprised that
Enterprise Linux isn't this way by default. If you are concerned about
someone getting root access to your computer by just sitting down to
it, then this is something you will want to install along with
setting a GRUB password.
