Customizing inittab and rc files for boot diagnostics

The following files are customized to diagnose how the MightyFrame is executing my customized /etc/inittab and /etc/rc files while attempting to boot a version of CTIX5.11onb modified by Sasa Todorovic and renamed to CTIX5.11dbg

Click each link above to download the source file and examine. 




The concept in my modified /etc/inittab file is to display on the screen each line of the file just prior to its execution of that line. Thus the eXXX::bootwait:echo " in front of the exact text string that the line below it will execute.  Same exact concept with the modified /etc/rc file.

So, what is it going to take to get this thing to give me a user prompt? How about just a login that will take "root" as user? 

Well, I did get that, but only that, using this very different (tiny, as we call it) /etc/inittab file:

The whole file consists of only:

is:1:initdefault:

000:123456:respawn:/etc/getty tty000 9600
001:123456:respawn:/etc/getty tty001 9600


It produced this, the most significant part bolded by me:

MightyFrame loader version 11
Do you want to boot anything other than the default? y

However, no matter what login I type in, nothing works.  root, install, anything, nothing, it just keeps repeating itself on <enter>
