All I know about ZFS is that there are weird patent or closed source encumbrances or something. I hear it’s good, and it seems popular, I just avoid proprietary Oracle products.

As for btrfs, the only thing that’s claimed to be unstable is raid 5 or 6. And people use it in production saying the claims are overblown. I don’t. I use it in raid1 mode. But raid1 in btrfs doesn’t require a bunch of matching drives. It lets you glom together a number of mismatched disks and just puts every block on more than one of them. So it’s a nice cross between a raid and LFS or JBOD.

Just btrfs.

Mostly by being an ingredient-only house. If there’s nothing too convenient around and you’re hungry enough, you might be more inclined.

Also you can make big things that you can pick off of throughout the week. I used to make giant pot roasts, which are great because you just dump stuff on top of a roast and pop it in the oven for a couple of hours without having to fuss over it, and eat that for a day or so, get bored with it and make tacos with the meat, etc.
