So, for my first trick I thought I'd try to create a customized System Rescue CD (http://sysresccd.org/).

I've failed, so far, but here's what I've done.

Downloaded the PPC version. Followed the "How to make a customized kernel" instructions. Found that the PS3 doesn't really behave like a PPC in regards to the sysresccd, since there is no yaboot.conf or special Power boot partition. I've never looked at power architecture before, so I may just be ignorant here.

Downloaded the x86 version. Followed the "How to make a customized kernel" instructions. This went okay, except the part where I needed to cat imagefs through create_compressed_fs, so I ran that part on an x86 vmware image I have and made my ISO.

Where I am now:

I have this "hybrid" sysresccd that I can't seem to figure out how to make kboot use.

Are there any kboot gurus around?

sorry, this just cannot work. now you have x86 microcode on the cd. this cannot run on a PowerPC cpu like the Cell in the PS3.

sorry, for being less helpfull than you would expect :roll:

I thought that if I was able to recompile the PS3 kernel and 'make zImage' that I could just build the ISO with that and somehow configure kboot to use /dev/cdrom/boot/vmlinuz1, etc.

Are you saying that running the imagefs through cat on x86 is going to be the issue?
