+ | ====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. | ||
