Description Don Zickus 2006-06-30 15:47:58 EDT
Description of problem:
When enabling the kexec-tools using kickstart, upon the subsequent reboot the
tool will crash with a commandline overflow.  This is because the kickstart
kernel commandline is huge and the huge line is passed to kexec which adds even
more ridiculous number of parameters.  
The solution is to not pass the kickstart info to kexec.

The patch is attached.  It has been discussed by Jeff Moyer, Vivek Goyal and
myself.  After much debate, we all agreed this patch is the way to go for now.

yeah, I don't like that we don't automatically build a command line on install,
but I don't see a better way around it at the moment.  Checked in for fc5 &
