We strive for perfection. Any goal less than that is sortof silly. But we are also realistic. Not everything is going to be perfect. This page documents what we know is broken, or not living up to it's potential.

system-config-packages

This is a graphical package manager designed to install packages from CD.
Limitation : It does not work. It is only included to satisfy dependancies. Recommended replacement is Yumex.
Recommendation : If you need a graphical installer, yumex is recommended. But it does not install packages from a CD.

up2date

Designed to automatically query servers to determine if updates are needed.
Limitation : up2date is not supported in Scientific Linux. It is only included to satisfy dependancies. It may or may not work. Recommended replacement is yumex-applet.

ipw3945

Wireless driver, firmware and deamon for the Intel ipw3945 wireless chipset
Limitation : Does not work in the installer. Does not work on all laptops.

3ware 8xxx and 9xxx in same system

3ware 8xxx and 9xxx are both IDE cards, and the drivers for both in the installer.
Limitation :Grub can get confused about which "drives" are which if both of these cards are installed. You can either run grub manually before rebooting or use "noprobe" during the install and install only the 3ware driver for the card that you will be booting off of.

Virtulization

Scientific Linux 4.5 and above have a xen kernel. This allows them to be installed as a xen paravirtulizaed guest. Follow the Virtual Host's instructions for installing a paravirtulizaed guest, to install Scientific Linux 4.5 as a xen guest.
Scientific Linux 4.5 can not be a xen host, only a guest.

Paravirtualizaed guests on Scientific Linux 5.0

This is a limitation of Scientific Linux 5.0, but affects installing Scientific Linux 4.5 as a paravirtulized guest. These limitations will hopefully be fixed in Scientific Linux 5.1 or 5.2

• 32 bit (i386) paravirtualized guests cannot run on a 64 bit (x86_64) host (dom0). It will fail.
• 64 bit (x86_64) paravirtualized guests cannot run on a 32 bit (i386) host (dom0). It will fail.

Fully Virtualizaed guests on Scientific Linux 5.0

This is a limitation of Scientific Linux 5.0, but affects installing Scientific Linux 4.5 as a fully virtulized guest.

• 64 bit fully-virtulizaed guests cannot run on a 32 bit (i386) host (dom0). It will fail.
