I see the 3.21 firmware just released by Sony disables the ability for the Fat PS3 to boot Linux anymore. You can skip this update but then the PSN stops working and it's likely that future games might not work.
I have a US PS3 (60G) original. I have never booted up Linux nor even thought about it but this just rankles me since after I apply the update, that choice will be gone.
How do others feel about this? It's been done allegedly to increase security because some guy managed to hack the PS3 through 5% hardware (taking it apart) and 95% software.
