encryption and grub.cfg

https://guix.gnu.org/en/manual/en/html_node/Keyboard-Layout-and-Networking-and-Partitioning.html/html/body/div[1]/div[4]/div[5]/pre/text()tell that you can encrypt as such

https://guix.gnu.org/en/manual/en/html_node/Keyboard-Layout-and-Networking-and-Partitioning.html/html/body/div[1]/div[4]/p[11]/samp[2]tell you to set up esp as such

Now Guix setup grub.cfg in encrypted /boot/grub, but Grub needs it prior to decryption to know that it has to decrypt something and its path to begin with

So either the manual commands/instructions needs to be corrected accordingly to avoid that issue. Either I haven't understood correctly how Grub can work in that disposition, either I haven't understood the manual right and haven't applied right the instructions
