FSTAB(5)                                   File Formats                                  FSTAB(5)

       fstab - static information about the filesystems


       The  file  fstab  contains  descriptive  information  about the filesystems the system can
       mount.  fstab is only read by programs, and not written; it is  the  duty  of  the  system
       administrator to properly create and maintain this file.  The order of records in fstab is
       important because fsck(8), mount(8), and  umount(8)  sequentially  iterate  through  fstab
       doing their thing.

       Each  filesystem  is  described  on a separate line.  Fields on each line are separated by
       tabs or spaces.  Lines starting with '#' are comments.  Blank lines are ignored.

       The following is a typical example of an fstab entry:

              LABEL=t-home2   /home      ext4    defaults,auto_da_alloc      0  2

       The first field (fs_spec).
              This field describes the block special device or remote filesystem to be mounted.

              For ordinary mounts, it will hold (a link to) a block special device node (as  cre‐
              ated  by  mknod(8)) for the device to be mounted, like `/dev/cdrom' or `/dev/sdb7'.
              For NFS mounts, this field is :, e.g., `knuth.aeb.nl:/'.   For  filesys‐
              tems with no storage, any string can be used, and will show up in df(1) output, for
              example.  Typical usage is `proc' for procfs; `mem', `none', or `tmpfs' for  tmpfs.
              Other special filesystems, like udev and sysfs, are typically not listed in fstab.
