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_afs_no_dynroot

This package removes the -dynroot option from the openafs config
Restarting of afs is needed for this to take effect.
This rpm does not restart afs

Who Needs This?
Machines that have openafs installed, but have problems with dynroot. This can happen if a particular site needs to have the afs root loaded all the time.
If you use the fnal.gov, and use upd/ups, you will need this rpm.

SL_desktop_tweeks

This adds a terminal icon to the kicker panel for both KDE and GNOME.
Changes the KDE splash background from red to black.
Installed by default for both KDE and GNOME.

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.

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.

SL_no_colorls

Turns off "color" of ls.

Who Needs This?
People who don't like the colorized ls

SL_password_for_singleuser

Changes /etc/inittab to require the root password for single user mode.
This used to be called SL_inittab_change

Who Needs This?
In my opinion everyone, and we're quite supprised that Enterprise Linux isn't this way. 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.

SL_rpm_show_arch

Adds architecture output to rpm query's.
Installed by default for x86_64 installs

Who Needs This?
Most x86_64 users, and anyone else who wants to know what architecture an rpm has been built for.

SL_sendmail_accept

Changes Sendmail config so that it allows incomming mail.

Who Needs This?
Machines that will be receiving e-mail.
