ReactOS can build itself
 

ow, ReactOS can fully build ReactOS, even with the USB stack. Be it a LiveCD or a BootCD! And just because we can, here LiveCD is mounted in ReactOS to show it. Thanks FreeBSD for your qsort implementation.

The building ReactOS wiki page has been updated with the new information. A pretty major milestone for any operating system!
