The config has an unencrypted /boot and an encrypted root. What’s
tested and known-good is a configuration with an encrypted root that
contains /boot, like the one here:
https://www.gnu.org/software/guix/manual/html_node/Using-the-Configuration-System.html#index-encrypted-disk-1
It may be that this configuration is not correctly supported yet.
I’m Cc’ing bug-guix@gnu.org so we keep track of this issue.

The passphrase-twice issue seems hard to avoid: first GRUB needs to
access the partition, and then the kernel needs to access it.
If anyone is aware of ways to solve this, I’m all ears!
Thanks for your report!

We have now pretty good LUKS support, but I don't know if we support
this use case. I always have `/boot` encrypted as well...

Unencrypted /boot and encrypted / is necessary to be able to use Heads
(right now).
(It measures /boot in order to find out whether it has been tampered with or
not)
If you want to be able to boot on a Heads system, either Heads needs to be
modified to mount encrypted / , or there needs to be an unencrypted /boot.

Hi,

(Off-topic.) I’d be curious to see how much of this approach makes sense
in the context of immutable deployments like Guix does.
