Prior to the slimmer PS3 models, you were allowed to install your own operating systems to Sony’s console. Those days are numbered now, as Sony has announced that firmware update 3.21 will arrive on April 1st, and it will eliminate the ability to install your own operating systems, namely Linux.

Why? Sony’s worried about security concerns with other operating systems. Technically, you could just avoid the firmware update should you want to keep using Linux, but by doing so you will no longer be able to sign into the PlayStation Network, use features that require signing into the PlayStation Network, or play games or Blu-ray movies the require firmware newer than 3.21.

If you have Linux on your PS3 but plan to comply and upgrade, you’re advised to back-up any data on your Linux partition, since you’ll no longer be able to access it after the update.
