This text exists in the man page: “Note that Btrfs subvolume mounts are handled internally in the kernel as bind mounts (see btrfs-subvolume(8)), and thus, may get skipped if you have also mounted the filesystem root itself. To counteract this, make your root directory a Btrfs subvolume, too.” > Also, it would be nice to have an explanation of the --debug-pruning output.

Nice job! locate needs 28 seconds? That's really, really slow unless you have thousands of hits. It should be on the order of milliseconds. updatedb could very well be in that range. /* Steinar */ -- Homepage: https://www.sesse.net/
