CentOS - Apr 2010 - Simplifying making a USB install key

Ok, where/how do I submit this to the CentOS project?

Here's a complete script - anyone, *please* feel free to test it, and let
me know if I've missed anything.

Thanks in advance.

   echo "usage: $0 <devname> <path/to/install.iso>"
   echo "  Example: $0 sdb /scratch/CentOS-5.4-bin-DVD.iso"
   echo "  Note: you must install livecd-tools before running this."
   exit
fi

If you don't want to jump through the hoops required to become a Wiki 
author, let me know and I'll be glad to add it with attribution to

Don't forget to say in the wiki where to get this
'livecd-iso-to-disk' fedora script

Variation on your theme.  Uses ext2 and extlinux with no FAT partition. 
   Remove "-n" from sfdisk so changes are written.  Adds some error 
checking.:

Unfortunately the only system I have to test on at the moment boots the 
installer OK, then asks for the installation media, but doesn't see the 
USB device when Hard Disk is selected.  With the FAT partition and 
syslinux doesn't see the device as bootable at all.
