    still encrypting filenames is...pretty abstract to me. if you want to hide files that badly, maybe entire encrypted partition would be more reasonable.

    libdrm 2.4.5

    no framebuffer drivers loaded.

    However, trying modesetting in this release is not easy. In the kernel side, only the Intel driver is getting modesetting support in this release (support for other drivers is being worked on and will be merged in future releases). In the X.org side, it's even more difficult. Because when the kernel modesetting support is enabled, it is REQUIRED that the X.org driver also has modesetting support. If you enable kernel modesetting and you don't have a modesetting-enabled driver, X.org will NOT be able to work in any way and it even may crash your machine. There's no way to workaround this, except disabling kernel modesetting (running a modesetting enabled X.org driver in a modesetting disabled kernel is allowed). Right now, only the Intel driver seems to have a stable release with modesetting support, alpha support is being worked on for other drivers.
    Looking at the X.Org versions you've got installed, you're probably running too old of X.Org and xorg-video-intel. Once those are up to speed, you should be able to get it all working together.

    I don't know, online fsck and defragmentation might actually make it viable for storage of smaller files. I could certainly go for a filesystem that does that well; my collection of internet memes is burgeoning. :P

    Ignoring the seemingly paranoid aspects of the first part and the general cannot-parse-ness of the end there, you make a good point about SSDs changing the way we manage on-disk formats, at least in the near term. My thought is it's not inconceivable that an SSD-optimised ext4 will come out in the next year or so. Indeed, I rather expect that there are already people working on this issue. Though really, I expect the SSD to move away from the current NAND Flash in a few years anyway.
    Defragmentation is welcome as well but really only applies to platter drives which are probably on the way out. Unless of course the people with the monsterous databases intend to buy up all the monsterously fast disk drives for a long time before we get access to them.
    Online fsck will help some people but I still would like there to be plenty of opertunity for the huge database crowd to have their databases fsucked for any and all likely and unlikely reasons. Including but not limited to massive solar flares, genetically modified electro-kitten attacks, extended power outages, etc etc.

    I wouldn't count it out. Even RAM (or virtual address space) fragmentation is a serious problem with some applications.

    Thankfully Linux devs introduced patches few releases ago to prevent RAM fragmentation.

    Didn't think about it that way. Learn something new every day.
