If the -.B single -option is used, or if the file -.I /etc/singleboot -exists, then single user mode will be entered, by starting -.IR /bin/sh . -If the file -.I /etc/securesingle -exists, then the root password will be required to start single user mode. -If the root password does not exist, or if -.I /etc/passwd -does not exist, the checking of the password will be skipped. - -If the file -.I /etc/TZ -exists, then the contents of that file will be read, and used to set the TZ -environment variable for each process started by -.BR simpleinit . -This "feature" is only available if it's configured at compile-time. It's -not normally needed. - -After single user mode is terminated, the -.I /etc/rc -file is executed, and the information in -.I /etc/inittab -will be used to start processes. Alternatively, the \fI/etc/inittab\fP -file may be configured to run a different boot script. See below for -details. - -.SH "THE INITTAB FILE" -Because of the number of init programs which are appearing in the Linux -community, the documentation for the -.I /etc/inittab -file, which is usually found with the -.BR inittab (5) -man page, is presented here: - -The format is - -.RS -.B bootprog=file - -.B fileprefix=string - -.B PATH=search path - -.B INIT_PATH=search path - -.B "ttyline:termcap-entry:getty-command" - -.B finalprog=path -.RE - -An example is as follows: - -.nf -.RS -bootprog = -fileprefix = /sbin/init.d/ -PATH = /usr/sbin:/usr/bin:/sbin:/bin -INIT_PATH = /sbin/init.d - -tty1:linux:/sbin/getty 9600 tty1 -tty2:linux:/sbin/getty 9600 tty2 -tty3:linux:/sbin/getty 9600 tty3 -tty4:linux:/sbin/getty 9600 tty4 -# tty5:linux:/sbin/getty 9600 tty5 -# ttyS1:dumb:/sbin/getty 9600 ttyS1 -# ttyS2:dumb:/sbin/getty -m -t60 2400 ttyS2 - -finalprog = /sbin/rc.xdm -.RE -.fi - -Lines beginning with the -.B # -character are treated as comments. Please see documentation for the -.BR getty (8) -command that you are using, since there are several of these in the Linux -community at this time. - -The \fBbootprog\fP value is appended to the \fBfileprefix\fP value, -and the result specifies the boot programme (script) to run. If -unspecified, the default is \fI/etc/rc\fP. If the boot programme is a -directory, then all scripts in that directory tree are executed, in -parallel. See the \fBneed\fP(8) programme for details on how to -elegantly control order of execution and manage dependencies. - -The \fBPATH\fP value is assigned to the PATH environment variable of -child processes (boot scripts). - -The \fBINIT_PATH\fP value is used by simpleinit(8) itself to find the -location of scripts to run (if an absolute path is not given). If -unset and the boot programme is a directory, that directory is used. -Finally, if the script cannot be found in this path, the standard -\fBPATH\fP is used. This separation allows boot scripts to invoke -programmes of the same name without conflict and without needing to -specify absolute paths. - -The \fBfinalprog\fP value specifies the path of the programme to run -after all \fBgetty\fP(8) instances are spawned. At bootup, it is -passed a single argument: "start". At shutdown, it is called again, -this time with the argument: "stop". -.SH SIGNALS -\fBsimpleinit\fP(8) responds to signals in a variety of ways: -.TP -.B SIGHUP -The \fI/etc/inittab\fP configuration file will be read again. -.TP -.B SIGTSTP -This flips a toggle, which controls whether more processes will be -spawned. -.TP -.B SIGINT -\fBsimpleinit\fP(8) will sync a few times, and try to start -\fBreboot\fP(8). Failing this, it will execute the system -\fBreboot\fP(2) call. Under Linux, it is possible to configure the -Ctrl-Alt-Del sequence to send a signal to the \fBinit\fP process -instead of rebooting the system (\fBsimpleinit\fP(8) does this by -default). -.TP -.B SIGQUIT -The \fBreboot\fP(8) programme is executed in place of the -\fBsimpleinit\fP(8) programme. This allows \fBreboot\fP(8) to cleanly -remount (read-only) the root filesystem, even if the old inode for the -\fBinit\fP process was unlinked. -.SH FILES -.I /etc/inittab -.br -.I /etc/singleboot -.br -.I /etc/securesingle -.br -.I /etc/TZ -.br -.I /etc/passwd -.br -.I /etc/rc -.SH "SEE ALSO" -.BR inittab (5), -.BR ctrlaltdel (8) -.BR reboot (8), -.BR termcap (5), -.BR getty (8), -.BR agetty (8), -.BR shutdown (8), -.BR initctl (8) -.SH BUGS -This program is called -.B simpleinit -to distinguish it from the System V compatible versions of init which are -starting to appear in the Linux community. -.B simpleinit -should be linked to, or made identical with, -.I init -for correct functionality. -.SH AUTHOR -Peter Orbaek (poe@daimi.aau.dk) -.br -Version 1.20, with patches for singleuser mode by Werner Almesberger -.br -Richard Gooch <rgooch@atnf.csiro.au> -.br -Dependency support - -.SH AVAILABILITY -The simpleinit command is part of the util-linux package and is available from -ftp://ftp.kernel.org/pub/linux/utils/util-linux/. |
