== Noteworthy SL Changes Since SL 6 ==
NOTE: This section documents changes made to SL specific packages since
      the SL 6 release. +
      This section does not list changes inherited from Upstream unless
      absolutely necessary.

=== No Longer Packaged By SL ===
.alpine
The alpine package is present in EPEL7.

.SL_desktop_tweaks
The default configuration provided by upstream already fulfills this function.

.SL_password_for_singleuser
The default configuration provided by upstream already fulfills this function.

.yum-autoupdate
With SL7 yum-cron has nearly all the functionality of yum-autoupdate and +
features upstream support.  The yum-autoupdate code should still function on +
SL7; however, we do not include it within the release. +

=== No Longer Packaged By Upstream ===
.krb5-appl
These legacy kerberos services are no longer packaged with the upstream product.
A request for EPEL7 has been filed in the upstream bugzilla (BZ#1130608)

=== SL Specific Behavior Changes ===

.SL-7-Install-Dual-Layer-DVD-x86_64.iso
The Dual Layer DVD image requires a Dual-Layer (DL) compatible
drive for both burning and booting off of.  This image can be link:#_how_to_make_a_bootable_usb_installer[converted to USB].

.sl-release and yum-conf-sl7x
The official SL repos are now packaged as one repo per config file.  In this way
customizations that you make to a specific repo will not prevent others from
being updated.

A further change in SL7 is the +sl7-fastbugs+ repo, featuring bugfixes and enhancements,
is enabled by default.  In SL6 it was installed, but disabled by default.
Your changes to this repo will persist through system upgrades if you wish to alter it.

Also, the SL repos now utilize the yum variable +$slreleasever+ in their config entries.

Since those changes are in place, SL 7 installs +yum-conf-sl7x+ by default.

You may wish to review the section on link:#_using_sl_yum_variables[Using SL Yum Variables].

=== Upstream Specific Behavior Changes ===

.systemd
Following upstream SL7 uses systemd as its init system.  The

published by upstream provides a helpful introduction to systemd commands.
