Games Pretty cool stuff: the PlayStation 4 apparently runs on a version of FreeBSD 9.0 modified by Sony and renamed to 'Orbis OS'. Second generation developer kits use GNU GRUB to boot, and allow you to boot into a graphical or a console mode. Not much else is known at this point, but it's a fun bit of information, and perhaps a boon to homebrew developer and hackers.

RE[2]: GRUB 2

No, the GPLv3 has an anti-tivoization clause. You need to give people access to the build-system and any signing keys used to sign the software. The guess here is that Sony wouldn't want to ship the PS4 with an unlockable bootloader.

Although they could use the BSD licensed OS parts to check if the GRUB bootloader has been altered and then refuse to load the rest of the system. That would technically satisfy the licensing stipulations on GRUB2. It probably would really mess up RMS's day though...
