@lritter @drq @Truck Nah, getting to the core of it: I think immutable is the kind of thing that contaminates FOSS spaces with gigantic blobs that nobody dares to look into and in the end can't rebuild, because it's expressly intended to not be tinkered with by anyone else.

Docker containers are the prime example of this but are sadly not alone.

Meanwhile I've been wishing since ~2008 for Linux distros to get their head out of their ass and adopt things like snapshots with proper system integration.
Something which OpenSolaris showcased and AFAIK macOS also integrated ages ago.
