While the install went OK, I am not (yet) convinced it was worth the hassle. While it’s nice to pick up bug fixes, I haven’t noticed much change to the feature set.
In summary, while FC8 and FC11 worked out of the box, FC12 failed to provide me with sound. I discovered later that the KDE mixer had set the center volume to mute. Once I unset that, I had sound.
Other than that, it worked pretty well.
In between bouts of Wipeout HD, I net-installed english-language 64-bit PowerPC Fedora Core 12 on my 80GB PS3. Installation with PetitBoot didn’t present any problems, though audio didn’t seem to work. However FC12 is quite slow on my PS3, so I ain’t going to use it – it seems it’s paging to disk a lot.
