I use btrfs for several years now — not with Guix System, though I do have Guix installed on top of Ubuntu on btrfs so I do have /gnu/store on btrfs. My experience is that it is zero-maintenance, at least on a personal laptop workload. Btrfs has matured a lot over the years, so there’s a fair amount of outdated advice still floating around on the Internet. You’re probably thinking of the ‘btrfs balance’ command. In the past, it was useful to run it every once in a while to avoid spurious ENOSPC errors. This problem has since been fixed, and current advice is that regular use of “btrfs balance” is now considered detrimental rather than beneficial since it puts more load/stress on the disk without any practical benefit. -- Thanks, Thiago
