.TH INIT 8 .SH NAME init \- initialize machine upon booting .SH SYNOPSIS .B /$cputype/init [ .B -ctm ] [ .I command ... ] .SH DESCRIPTION .I Init initializes the machine: it establishes the name space (see .IR namespace (4) and .I newns in .IR auth (2)), and environment (see .IR env (3)) and starts a shell .RI ( rc (1)) on the console. If a .I command is supplied, that is run instead of the shell. On a CPU server the invoked shell runs .IR cpurc (8) before accepting commands on the console; on a terminal, it runs .IR termrc and then the user's profile. Options .B -t (terminal) and .B -c (CPU) force the behavior to correspond to the specified service class. Otherwise .I init uses the value of the environment variable .B $service to decide the service class. .PP .I Init sets environment variables .B $service (either to the incoming value or according to .B -t or .BR -c ), .B $objtype (to the value of .BR $cputype ), .B $user (to the contents of .BR #c/user ), and .B $timezone (to the contents of .BR /adm/timezone/local ). .PP With option .B -m .I init starts only an interactive shell regardless of the .I command or service class. .PP On a CPU server, .I init requires the machine's password to be supplied before starting .I rc on the console. .PP .I Init is invoked by .IR boot (8), which sets the arguments as appropriate. .SH SOURCE .B /sys/src/cmd/init.c .SH "SEE ALSO" .IR rc (1), .IR auth (2), .IR boot (8)
