Where do I add a kernel parameter to mount encrypted root partition?

I'm setting up a new system using GRUB as the boot manager and an encrypted root partition. Apparently I need to have grub send a parameter to the kernel telling it to decrypt this partition, but I'm not sure where or how to add it. Looking at the GRUB docs, I see there is an entry in /etc/default/grub GRUB_ENABLE_CRYPTODISK, but that seems to be for having /boot on an encrypted partition. My /boot is on a separate UEFI partition.

Where and how do I tell the kernel to decrypt my root?

https://wiki.archlinux.org/title/Kernel_parameters#GRUB -- for configuring parameters and https://wiki.archlinux.org/title/Dm-cry … figuration for configuration settings you need to do. Which instructions did you follow to install this if you didn't run into this wiki page?

The Kernel_parameters page is linked to from the other page, which I gave you in the other thread. Why did you start a new one?
