Text used for examples, which is meant to be replaced with data provided by the user, is displayed
in this style. In the following example,
<

is displayed in this style:
The directory for the kernel source is
/usr/src/
<
version-number

/
, where
<
version-number
>
is the version of the kernel installed on this system.
Additionally, we use several different strategies to draw your attention to certain pieces of information.
In order of how critical the information is to your system, these items are marked as a note, tip,
important, caution, or warning. For example:
Note
Remember that Linux is case sensitive. In other words, a rose is not a ROSE is not a rOsE.
Tip
The directory
/usr/share/doc/
contains additional documentation for packages installed on your
system.
Important
If you modify the DHCP configuration file, the changes do not take effect until you restart the DHCP
daemon.
Caution
Do not perform routine tasks as root — use a regular user account unless you need to use the root
account for system administration tasks.
Warning
Be careful to remove only the necessary Red Hat GFS partitions. Removing other partitions could
result in data loss or a corrupted system environment.
