+======Runlevel======
+====Overview====
+(from wikipedia)
+the term **runlevel** refers to the mode of operation in an OS that implements the Unix System V-style initialization.
+runlevel defines the state of the machine after boot. Different runlevels are typically assinged to the:
+   * single-user mode (root)
+   * multi-user mode without networking services started
+   * multi-user mode with networking services started
+   * system shutdown
+   * system reboot
+The real thing you should know about this: the **Linux Standard Base specification**.
+This is a general guide for what the run level ID's pair up too. In debian 2-5 are the same (full multi-user with console logins), RHEL is more secured but also a pain in the ass.
+<code>
+       Halt
+       Single-User mode
+       Multi-user mode (sin networking)
+       Multi-user mode (with networking)
+       Not generally used
+       Multi-user mode (with x & console)
+       Reboot
+</code>
+So by editing /etc/inittab , you could in theory have a program enter runlevel 6 and reboot the system. >;]~
