Subject: Unknown initrd commands

I have been digging around a few times online, and have not been able to find where some commands invoked from the Fedora init script are located.

The contents of the script are as follows along with some notes that I've added:

--------------------------------------------------------------------------------------------

#!/bin/nash

mount -t proc /proc /proc

setquiet
   # nash: cause any late echos in this start script not to be displayed

echo Switching to new root and running init.

switchroot
   # nash command

echo Booting has failed.
sleep -1

Where are these commands documented? Also, do initrd/nash have a home page? 

Thanks!
