Schnapps is just a frontend for btrfs. The magic is there and when you truly understand the filesystems mechanics then amazing things are possible like the multiple rootfs type setup on btrfs that the Omnia has. One would think all distributions should be like this.
It’s a very practical way to do things and is very true to the open source way by keeping options open for the user. Huge thumbs up to Turris team for this. I make btrfs read only snapshots of my systems and send them via ssh to a remote backup server as a subvolume ready to be deployed whenever needed. btrfs makes it simple and staying in the btrfs toolchain lets you keep all file attributes intact which to me is a major advantage in the sort of file integrity that can be important in applications.
I believe this sort of device is the key to good networks and network models coming into existence in a much bigger world of technology in the future. Machines like these that are fully open source and in the hands of a capable admin will be the backbone of good networks. They allow a higher level of privacy and service in a world always competing for greater and greater efficiency and diminishing returns.
