D. mount point; device name; filesystem type; mount options; dump filesystem; fsck order
E. device name; mount point; filesystem type; mount options; dump filesystem; fsck order

Each filesystem is described on a separate line; fields on each line are separated by tabs or spaces. Lines starting with #are comments.
