I don't think you can run bash directly from inittab, that's why we needed the 
mingetty patch, which allowed the console to autolog as any user.

I don't know what PROP is (maybe because I'm not a VM expert).

In the end, this mechanism didn't work very well because it was too easy for 
the console to get hung up.  We augmented it using a script run from cron that 
fed a web page, and later added Nagios.
