-<P>I bought a <A HREF="https://www.amazon.com/gp/product/B09B1JFY24/">SAMSUNG EVO Select 128GB New Generation</A> card (apologies for the Amazon link, it isn't an associate link though), wiped it, and put one partition on it that spanned the whole drive.</P>
-<P>See <A HREF="/knowledge/cryptography#luks_partitioning">cryptography#LUKS partitioning</A> for how to make a LUKS partition.</P>
-<P>
-To have the SD card auto-mount at boot, add an <CODE>fstab(5)</CODE> line for the decrypted block device.
-The <CODE>localmount</CODE> OpenRC service will also have to be enabled for the system to read <CODE>fstab(5)</CODE> - <CODE>rc-update add localmount</CODE>.
-Then, <CODE>rc-update add dmcrypt boot</CODE> and add an entry in <CODE>/etc/conf.d/dmcrypt</CODE> to automatically luksOpen the volume.
-<CODE>dm-crypt</CODE> will need the UUID of the <I>physical</I> block device; in <CODE>blkid(8)</CODE> this will be the line that starts with <CODE>/dev/mmcblk</CODE> or <CODE>/dev/sd[<I>X</I>]</CODE>.
