<para>Mount units may either be configured via unit
files, or via <filename>/etc/fstab</filename> (see
for details). Mounts listed in
<filename>/etc/fstab</filename> will be converted into
native units dynamically at boot and when the
- configuration of the system manager is reloaded. See
+ configuration of the system manager is reloaded. In
+ general, configuring mount points through

<para>When reading <filename>/etc/fstab</filename> a
few special mount options are understood by systemd
which influence how dependencies are created for mount
- points from <filename>/etc/fstab</filename>. systemd
- will create a dependency of type
- <option>Wants</option> from either
- <filename>local-fs.target</filename> or
+ points. systemd will create a dependency of type
+ <option>Wants</option> or <option>Requires</option>
+ (see option <option>nofail</option> below), from
+ either <filename>local-fs.target</filename> or
<filename>remote-fs.target</filename>, depending
- whether the file system is local or remote. If
- <option>x-systemd.automount</option> is set, an
- automount unit will be created for the file
- system. See

- should wait for a device to show up before giving up
