shure, our embedded systems usually run a few processes only, so we usually
run a DOS like Init scheme. Didn't run any QNX ever, so I don't have a clue
haow they handle startup.
In our case init just runs one startup script and there are some additional
logins started where necessary. One getty Process is enough most
of the time, you could even replace it with a bash running immediately.
Needless to say, that this shoul be done only if the console does not have
any public access.
Here is how a sample iniitab looks like. It could be handy to have some type
of network runlevel which could be entered for development purposes, when
you don't need the net in production use. rc.0, rc.2 etc. are the
autoexec.bat style files I was talking about.
