- These shell procedures are executed via entries in /_e_t_c/_i_n_i_t_t_a_b by
- _i_n_i_t(1M) whenever the system is booted (or rebooted).
-
- First, the _b_c_h_e_c_k_r_c procedure checks the status of the root filesystem.
- If the root filesystem is found to be bad, _b_c_h_e_c_k_r_c repairs it.
-
- Then, the _b_r_c procedure clears the mounted filesystem table, /_e_t_c/_m_t_a_b,
- and puts the entry for the root filesystem into the mount table.
-
- After these two procedures have executed, _i_n_i_t checks for the _i_n_i_t_d_e_f_a_u_l_t
- value in /_e_t_c/_i_n_i_t_t_a_b. This tells _i_n_i_t in which run level to place the
- system. Since _i_n_i_t_d_e_f_a_u_l_t is initially set to 2222, the system is placed in
- the multiuser state via the /_e_t_c/_r_c_2 procedure.
-
- Note that _b_c_h_e_c_k_r_c should always be executed before _b_r_c. Also, these
- shell procedures can be used for several run-level states.
