2 System configuration
Before using NeroLINUX you need to make sure that your system is correctly
configured. Please read the following instructions very carefully to make sure that
the first disc you record will be successful.
This chapter provides also some information about the way the Linux kernel
internally handles CD and DVD recorders, and how NeroLINUX handles them.
Some sections of this chapter are a little bit technical but we have tried to make
them easy to understand, even if you are not familiar with Linux environments.
Please note that all the examples and commands that are shown can
compromise your system security policy, especially when setting up the
permission on the device files.
2.1 Linux kernel version
2.1.1 Linux kernel version explanations
The kernel is the heart of your Linux system. It provides for example the low-level
drivers used to access your devices.
In order to identify your devices filenames clearly, you need to first know the
version of the Linux kernel you are currently using. To get it, open a terminal and
type the following command:
uname –r
The output of this command should give you three numbers separated by periods
(full stops), for example 2.6.7.
 The first number is the kernel version (2 in our example).
 The second number is the kernel major number (6 in our example). All
kernels that are considered “stable” have even major number. The kernels
with odd major number are development kernels.
 The last number is the kernel release number (7 in out example).
The Linux kernel version is often identified by the first two numbers, as there is
no significant change between two releases of the same kernel. So when you see
for example 2.4 kernel, it means a kernel with a version number of 2 and a major
number of 4.
