All of my important data is on btrfs drives. I intend to install my system on ZFS. Why, you may ask? Because I can. That's the fun of Linux after all. I intend to mount btrfs drives as well. I hear that ZFS can break fairly easily? Is this a bad idea?

Edit: I understand ZFS is out of tree but CachyOS maintains their own package and dkms so it shouldn't matter I would think?

In my limited experience running ZFS (daily driving FreeBSD with ZFS for two years, and also running Void Linux with ZFS for about a week quite recently), I always found it to be a nice filesystem that was decently fast and didn't break. I currently have a ZFS partition on an external disk, but that's just because I have some files with names longer than 255 bytes that I need to store, and I can't really use ReiserFS anymore. However, for my root partition, I usually opt for XFS (or JFS, on older machines).

It's also worth noting that my stack is weird. I tend to run well-known but less popular Linux distros on older hardware, normal usage sometimes breaks everything, and I could probably leave my laptop unlocked at uni because only about three other people know how to use my window manager. Also, the hardware itself has a habit of dying for a week or so and then miraculously self-repairing.
