Defining run-levels Introduction 11.. PPuurrppoossee _L_i_n_u_x_c_o_n_f provides five predefined run-levels generally suitable for workstations. Each run-level corresponds to a combination of the following features: +o Graphic mode, X-terminal, or text mode. +o Network or stand-alone mode. +o One run-level number as defined in /etc/inittab. Some _L_i_n_u_x systems need more control. Some servers never run X, for example, but may support various configurations through /etc/inittab. It is possible to reprogram the five definitions provided by _L_i_n_u_x_c_o_n_f. Each of the three topics above may be controlled separately for each of the five run-levels. You are also allowed to give a different name. 22..
