From what I can tell, Kexec is a way of booting a kernel while another is running.
http://en.wikipedia.org/wiki/Kexec
Kboot is a boot loader that uses kexec. Although the original project page is here:
http://kboot.sourceforge.net/
they appear to be using a fork known as ps3-kboot:
http://www.kernel.org/pub/linux/kernel/ ... ell/README
and others
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=503482
Traditionally, this has been what you load in the otheros.bld for most PS3 Linuxes. Kboot starts in the firmware, then switches to the kernel in the /boot directory on your hard disc. YDL 5.x used kboot.conf, YDL 6.x uses yaboot.conf.
I think YDL is still using kboot for the PS3 since it can read yaboot.conf files. See here: http://www.mail-archive.com/debian-powe ... 59396.html . They're probably just using yaboot.conf to simplify installations, since Macs would need it. kboot also contains busybox, which is why you can execute Unix commands at the kboot: prompt.
Yaboot is a PowerPC boot loader that is popular for Macs & IBMs. Again - I don't think YDL really uses Yaboot on the PS3 - just the yaboot.conf file structure. My guess is that YDL uses yaboot as the boot loader for Mac & IBMs. Since kboot can understand yaboot.conf, this makes sense.

There's an alternative GUI bootloader called Petitboot that some folks like:

Correct - to the best of my knowledge, the main part of the Cell/RSX/FlexIO and their associated RAM (XDR, GDDR3) is identical between the two models. The differences appear to be in the southbridge equivalent chipsets - things like the slim's Bravia-link capabilities, Dolby TrueHD & DTS master sound bitstream output, etc.

So install OtherOS and start playing around. If people start coming up with convincing reasons why they need the exploit to go further, I'll release it. It's just a waste to release if people can't make use of it.
