> On the topic of alternative btrfs implementations, I've been working on https://git.lukeshu.com/btrfs-progs-ng/ https://git.lukeshu.com/btrfs-progs-ng/ which is written entirely in Go. Is this actually a blessed "next-generation" implementation? If not, could you please rename it so it doesn't confuse people?

If it's better, it should just be named btrfs-progs so folks get confused into installing superior tools.

  First of all, I do intend for it to get incorporated in to upstream btrfs-progs. Plus, for the most part, it's not a replacement for what's in btrfs-progs, it's additional tools: Replace: - `btrfs-rec inspect dump-trees` is a clone of `btrfs inspect-internal dump-tree`, but it isn't meant to replace it, I only implemented it so that I could diff the output to validate that my implementation agrees with the btrfs-progs implementation. - `btrfs-rec inspect mount` is conceptually a replacement for `btrfs restore`. - `btrfs-rec inspect rebuild-mappings` is a replacement for `btrfs rescue chunk-recover` Additional: - I don't believe that `btrfs-rec inspect rebuild-trees` has an equivalent. - `btrfs-rec inspect list-nodes`, `btrfs-rec inspect ls-files`, and `btrfs-rec inspect ls-trees` have no equivalent in btrfs-progs. - (for completeness) `btrfs-rec inspect spew-items` has no equivalent, but it's for debugging btrfs-rec itself. Missing: - `btrfs-rec` doesn't try to do anything with mounted filesystems, such as `btrfs balance`, `btrfs filesystem`, `btrfs scrub`, `btrfs send`/`btrfs receive`, ... - `btrfs-rec` doesn't try to do anything with filesystem initialization, such as `btrfstune` or `mkfs.btrfs`. - `btrfs-rec` doesn't try to do things with recovering the superblock, I've found `btrfs rescue super-recover` and `btrfs-select-super` to be adequate. - In general, I didn't try to re-implement commands that already work well.

I intend for it to get incorporated in to btrfs-progs. In the mean-time: yeah, btrfs-progs-ng isn't a great name for the repo, but as I said, I isn't quite ready to publish it yet either, so the repo name wasn't at the top of my list. I originally had the repo named "btrfs-tools", but that's even more confusing (but for different reasons)! (As a side note, I've had others fork software I maintain and call it "-ng", you learn to take it as a compliment :) )
