    So many different kinds of filesystems now, I get confused. What's the difference between Ext4/XFS/Btrfs, OverlayFS, and TraceFS/debugfs?

      Hi mate, some are real disk drives file systems (for HDD or SDD). Some are virtual filesystems, in essence they are contained entirely in RAM, and serve a purpose. /proc is such system.

        Generally, you can find on root (/) a file system like Ext4, XFS or other.
        But on /proc, it is proc file system, on /sys it is sysfs, and on /tmp it is /tmpfs. And you can find DebugFS on /sys/kernel/debug.

        I love the possibility to mount a file system in another.

        Get a try of command 'mount' without arguments.

          In Unix, everything is a file - except the network interfaces, of course.

            Not quite sure where you are coming from there network interfaces are represented as files as well... as is your graphics card, sound card ad infinitum...

              Glendix tried to port the Plan9 /net to Linux. Unfortunately the project stalled. It would be cool if in the future everything really became a file Plan9-style (including IPC, network, "sockets" ...)

                Admins, servers... How about a robust, unbloated, modern file system for home users?

                  hmm modern but not bloaded is kind of the opposite

                  but ext4 and xfs are more modern than apples or microsofts filesystem and at least same robust and unbloatet...
