@bojanland@mastodon.online @nixCraft Arch lets you do anything you want and it's your responsibility to ensure it's not stupid and won't break your system. ZFS is not the default, but there's no actual default, just instructions on how to install it on a FS of your choice.

To be clear, that's not a critique nor an endorsement. It's just a system for different use cases than something noob-friendly like Ubuntu.
