-Note that GRUB can unlock LUKS2 devices since version 2.06, but only
-supports the PBKDF2 key derivation function, which is not the default
-for @command{cryptsetup luksFormat}.  You can check which key derivation
-function is being used by a device by running @command{cryptsetup
-luksDump @var{device}}, and looking for the PBKDF field of your
-keyslots.
+While efforts are in progress to extend support to LUKS2, please note
+that Guix only supports devices of type LUKS1 at the moment. You can
+verify that your existing LUKS device is of the right type by running
+@command{cryptsetup luksDump @var{device}}. Alternatively, you can
+create a new LUKS1 device with @command{cryptsetup luksFormat --type
+luks1 @var{device}}.

 cryptsetup open /dev/sda2 my-partition
