# Creating the /etc/fstab file

In order for certain programs to be able to determine where certain partitions are supposed to be mounted by default, the /etc/fstab file is used. Create a new file `/etc/fstab` containing the following:

    cat > /etc/fstab << "EOF"
    # Begin /etc/fstab

    # filesystem   mount-point fs-type    options     dump    fsck-order

    /dev/*LFS*     /           *fs-type*  defaults    1       1
    /dev/*swap*    swap        swap       pri=1       0       0
    proc           /proc       proc       defaults    0       0
    shm            /dev/shm    tmpfs      defaults    0       0

    # End /etc/fstab
    EOF

`*LFS*`, `*swap*` and `*fs-type*` have to be replaced with the appropriate values (/dev/hda2, /dev/hda5 and reiserfs for example).

When adding a reiserfs partition, the `1 1` at the end of the line should be replaced with `0 0`.

A tmpfs mount is added at /dev/shm to comply with Posix shared memory requirements. For more information, see the file Documentation/filesystems/tmpfs.txt in the kernel source tree.

For more information on the various fields which are in the fstab file, see `man 5 fstab`.

There are other lines which you may consider adding to your fstab file. One example is the line which you must have if you are using devpts:

    devpts         /dev/pts    devpts     gid=4,mode=620 0    0

Another example is a line to use if you intend to use USB devices:

    usbfs       /proc/bus/usb usbfs defaults    0       0

Both of these options will only work if you have the relevant support compiled into your kernel.
