I used it quite often in RHEL to kick off a zero-touch anaconda (re)install 
from a booted workstation.  I had a script drop off important parsable data in 
the EFI partition and the kickstart %pre would read it in to handle the zero 
touch. 

These were dual boot so it was mostly to avoid dealing with the windows 
install.
