[CentOS] How can kickstart be (re)started manually from the dracut emergency shell?

Hi,

this is a side question to my other thread regarding dracut-initqueue 
network issues.  Once I'm thrown into a dracut emergency shell (PXE 
booted system): How can I restart the kickstart installation process 
manually from there?  Can I at all?

Background is, that I'd like to add some debugging output to some of the 
dracut scripts and rerun the installation process to see why it fails.

Thanks
frank
