Fond of your classic PS3's ability to load Linux? Then don't accept the update that Sony is pushing on you.
Those of you logging onto the PlayStation Network today with your PS3s will notice a request to update your system firmware to 3.21. If you have no intention of ever running Linux on your console, then feel free to update – but be warned that this new update will remove the "Other OS" capability. Read here for more.
Of course, those who are interested in staying up to date and still be able to partake on PSN may have to wait for a hacked custom firmware solution. We don't know if it's possible yet, but this one hacker is currently working on it.
Don't forget to check out what John Carmack thinks of this latest move by Sony in our feature of Why You Should Care that Linux is ditched.

That man is a genius.
Not about that... ultimately, it's about freedom of choice.
Don't give me that bullshit.
I normally don't care about people pirating, but in this case piracy on the PS3 would spell doom for Custom software. GeoHot isn't interested in it, and neither am I. In the horrid outcome that people start PS3 Piracy, Sony will work to destroy all CFW regardless of it purpose and intent.
They may try initially, but if they find there isn't any CFW that allows piracy, they may ease up, maybe even meet the community half way, realizing their reaction was inappropriate.
If you don't want your userbase being angry at you for having less choices, don't give them choices to begin with only to take them away later.
