I'm not entirely sure I understand the above. It sounds like someone is claiming that: * Archiving programs should know about the *timing* of filesystem implementations (60s here for btrfs, something else for <new filesystem XYZ>?) * And specifically request the OS to fsync() files before trusting the metadata Huh?
