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?
I disagree about it being a sword as a letter opener for an OS drive. An OS drive is where it shines, where you can rollback upgrades and corruption with snapshots, where large logs live compressed in storage without second thought, where storing two copies of critical OS files or mirroring across two drives defeats corruption from drive sectors going bad or in the later case prevents downtime and data loss from the OS drive dying.
If you want to argue it can be a headache to boot on ZFS on Linux I’ll agree but using its feature set to argue against it makes no sense.
It’s the default filesystem for the OS over in the BSD world, where reliability and stability surpasses linux
