is a generator that translates

<filename>/etc/crypttab</filename> into native systemd
|
|
units early at boot and when configuration of the
|
|
system manager is reloaded. This will create

<citerefentry><refentrytitle>systemd-cryptsetup@.service</refentrytitle><manvolnum>8</manvolnum></citerefentry>
|
|
units as necessary.</para>
