Currently it doesn't require (and is unable to -perform) any authentication, but this is easy to add if needed. - -Standard version of FreeBSD kernel looks for /sbin/init first, and then -tries to execute it. If it fails, it tries to find: - /sbin/oinit - /sbin/init.bak - /stand/sysinstall - -So it is easy to make use of it even on standard system - just put it in -/sbin/oinit and rename /sbin/init to something else, e.g. /sbin/init.bak. - -+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ -!!!

Built-in commands -are listed below. For each command there is short help available, with -example of usage. - - cd change working directory - pwd print working directory - set set environment variable (no expansion) - unset unset environment variable - env print all environment variables - echo echo arguments on stdout - exit exit from shell (oinit will start a new one after some delay) - . source-in a file with commands - ? help - -Any other command is passed to execvp(3) as it is. - -EXCEPTION: if you end the command line with a '&', the command is started -as daemon. This is NOT the same as in normal shell, where the '&' puts a -process in background.

(it depends on how much memory it needs). - * programmatic hooks for easy customisation of user interface (like - hierarchy of commands and contexts), - * ... - -- implement as a routine (like shell()) a small remote login daemon telnet(), - as a built-in module to oinit. It would implement the simplest options of - normal telnet, and would itself handle authentication, passing control to - shell() on success. The authentication routine would be the same as for - checking console access. - -And allow me for a moment of day-dreaming: I'd like to rewrite oinit one day -to be a monolithic one-in-all application, non-forking but multithreaded...
