SELinux has two major components on your system. There's the kernel mechanism which is enforcing a bunch of access rules which apply to processes and files. And secondly, there's file labels : every file on your system has extra labels attached to it which tie-in with those access rules. Run ls -Z and you'll see what I mean.
Should you really disable SELinux?
Be aware that by disabling SELinux you will be removing a security mechanism on your system. Think about this carefully, and if your system is on the Internet and accessed by the public, then think about it some more. Joshua Brindle (an SELinux developer) has comments on disabling SELinux here, which states clearly that applications should be fixed to work with SELinux, rather than disabling the OS security mechanism.

This article will try to explain how to install SUSE Linux 10.2 with software RAID.
If you want to install the kind of RAID that is supported by some motherboards (so called fakeRAID), just enable RAID in your BIOS and install as usual. NOTE: This only applies to openSUSE 10.2 or later. Earlier versions of SUSE DO NOT support fakeRAID
