RC(8)               UNIX Programmer's Manual                RC(8)

NAME
     rc - command script for auto-reboot and daemons

SYNOPSIS
     /etc/rc [ autoboot | fastboot [ powerfail ] ]

DESCRIPTION
     _R_c is the command script which controls the automatic
     reboot.

     When an automatic reboot is in progress, _r_c is invoked by
     /_e_t_c/_i_n_i_t with the first argument _a_u_t_o_b_o_o_t and runs _f_s_c_k
     with option -p to ``preen'' all the disks of minor incon-
     sistencies resulting from the last system shutdown and to
     check for serious inconsistencies caused by hardware or
     software failure.  If this auto-check and repair succeeds,
     then the second part of _r_c is run.

     The second part of _r_c, which is run after a auto-reboot
     filesystem check succeeds and also if _r_c is invoked when a
     single user shell terminates (see _i_n_i_t(8)), starts all the
     daemons on the system, preserves editor files and clears the
     scratch directory /_t_m_p. _S_a_v_e_c_o_r_e(8) will be run to check for
     a system core dump, and, if found, save the dump in
     /usr/sys.  The second argument may be _p_o_w_e_r_f_a_i_l if the sys-
     tem went down due to a power failure.

SEE ALSO
     init(8), reboot(8)

BUGS
     After making changes to the root file system, the system
     must be rebooted to keep the incore copy of the super-block
     from corrupting the newly computed super-block.

     It should be possible to print a message about power failure
     much earlier than from /etc/rc.
