While I am a big fan of Intel's Clear Linux distribution for its raw performance on x86_64 hardware that for most workloads goes unsurpassed by any other Linux platform out-of-the-box, there has been a lot of Phoronix readers wondering how well it could function as a standard desktop Linux distribution. With upgrading my main production system earlier this month, I decided to try out Clear Linux and now with 200+ hours into using it as the OS on my main production system, I figured it'd be good to share my initial thoughts.
One of the recent XFS innovations under work and maturing with time has been Copy on Write (CoW) support for this mature Linux file-systems. The XFS CoW support continues to be improved upon and an "always CoW" option is being prepared to always force this behavior.
