Tweak RPM's

Tweak RPM's can be added to change a feature without disturbing the rest of the release.

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.


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, and use upd/ups, you will need this rpm.


This adds a terminal and mozilla icon to the kicker panel for both KDE and GNOME.
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.


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.


This script removes the .parentlock file upon startup for firefox, thunderbird, or seamonkey.

Who Needs This?
Users who's home area is in AFS space, and are using firefox, thunderbird, or seamonkey.


Changes /etc/inittab to require the root password for single user mode.

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.


Creates a missing symbolic link in the gcc-g77 package from
to /
Installed with gcc-g77

Who Needs This?
Fortran coders


Turns off "color" of ls.

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


Changes Sendmail config so that it allows incomming mail.

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


By default startkde checks to make sure that a users home area has at least 25K of disk space. A bug in the openafs kernel module for the enterprise kernel causes single cpu machines to only list 1 K of space. This changes the check to only need 1 K of space. The check to make sure kde can actually write to the users home area is still intact.

Who Needs This?
People who's home area is in AFS space, and are using KDE.


Enables gnome to work better in a afs envirnonment.

Who Needs This?
People who's home area is in AFS space, and are using Gnome.


Setup thunderbird to use firefox as it's default url handlers. This means that when you click on a web or ftp link in an e-mail, it will bring up firefox.

Who Needs This?
People who want to use both thunderbird and firefox.


For the RedHat kernel 2.4.21-9.EL and above, many people feel that the kernel isn't very responsive on desktops. This tweek changes the pagecache settings. This has been shown to make the kernel seem much more responsive in a desktop enviroment. Values changed to "1 5 10" for /proc/sys/vm/pagecache .
This parameter has three values :
* Minimum percent of memory used for page cache. Default is 1%.
* The initial amount of memory for cache. Default is 15%.
* Maximum percent of memory used for page cache. Default is 100%

Who Needs This?
Desktop users who feel like their machine is swapping more than it should.
