<title>File Systems</title>
<para>
You can define file systems using the <literal>fileSystems</literal>
configuration option. For instance, the following definition causes
NixOS to mount the Ext4 file system on device
<literal>/dev/disk/by-label/data</literal> onto the mount point
<literal>/data</literal>:
</para>
<programlisting language="bash">
fileSystems.&quot;/data&quot; =
{ device = &quot;/dev/disk/by-label/data&quot;;
fsType = &quot;ext4&quot;;
};
</programlisting>
<para>
This will create an entry in <literal>/etc/fstab</literal>, which
will generate a corresponding
<link xlink:href="https://www.freedesktop.org/software/systemd/man/systemd.mount.html">systemd.mount</link>
unit via
<link xlink:href="https://www.freedesktop.org/software/systemd/man/systemd-fstab-generator.html">systemd-fstab-generator</link>.
The filesystem will be mounted automatically unless
<literal>&quot;noauto&quot;</literal> is present in
<link linkend="opt-fileSystems._name_.options">options</link>.
<literal>&quot;noauto&quot;</literal> filesystems can be mounted
explicitly using <literal>systemctl</literal> e.g.
<literal>systemctl start data.mount</literal>. Mount points are
created automatically if they don’t already exist. For
<literal>device</literal>, it’s best to use the topology-independent
device aliases in <literal>/dev/disk/by-label</literal> and
<literal>/dev/disk/by-uuid</literal>, as these don’t change if the
topology changes (e.g. if a disk is moved to another IDE
controller).
</para>
<para>
You can usually omit the file system type
(<literal>fsType</literal>), since <literal>mount</literal> can
usually detect the type and load the necessary kernel module
automatically. However, if the file system is needed at early boot
(in the initial ramdisk) and is not <literal>ext2</literal>,
<literal>ext3</literal> or <literal>ext4</literal>, then it’s best
to specify <literal>fsType</literal> to ensure that the kernel
module is available.
</para>
<note>
<para>
System startup will fail if any of the filesystems fails to mount,
dropping you to the emergency shell. You can make a mount
asynchronous and non-critical by adding
<literal>options = [ &quot;nofail&quot; ];</literal>.
