14 *fsck.btrfs* is a type of utility that should exist for any filesystem and is
15 called during system setup when the corresponding `/etc/fstab` entries
16 contain non-zero value for `fs_passno` , see `fstab`(5) for more.
18 Traditional filesystems need to run their respective fsck utility in case the
