Perhaps this needs to be taken up with the Freedom Box Foundation (it has close ties to Debian) as it is the image they provide that chose btrfs to be written to the micro-SD card and used as an appliance on the Freedom Box Pioneer hardware (Olimex A20-OLinuXino-LIME2). *I* did not choose this filesystem for this application, just to be clear. If there is a better choice for what is intended to be an appliance running from a micro-SD card, then that should be communicated to the Freedom Box people. I have an SSD on order and will rebuild with ext4. - Nate -- "The optimist proclaims that we live in the best of all possible worlds. The pessimist fears this is true."
