> 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

> 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

> This was added with SL 6.0 and continues in this release.
> Summary : Fast and small X11 window manager

> gtk+ - for dependencies
> glib - for dependencies

>
> abattis-cantarell-fonts
> This was added with SL 6.1 and continues in this release.

>
> glusterfs-server
> These became dependancies and were added as of SL 6.8.

> ---------------------------------------------------------------------------
> 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.
