+# fsck.btrfs is a type of utility that should exist for any filesystem and is
+# called during system setup when the corresponding /etc/fstab entries contain
+# non-zero value for fs_passno. (See fstab(5) for more.)
+#
+# Traditional filesystems need to run their respective fsck utility in case the
+# filesystem was not unmounted cleanly and the log needs to be replayed before
+# mount. This is not needed for BTRFS. You should set fs_passno to 0.
+#
+# If you wish to check the consistency of a BTRFS filesystem or repair a
+# damaged filesystem, see btrfs(8) subcommand 'check'. By default the
+# filesystem consistency is checked, the repair mode is enabled via --repair
+# option (use with care!).
