crypttab is some part of the LUKS encryption stuff. This appears to be a 
manpage for it: https://www.man7.org/linux/man-pages/man5/crypttab.5.html

The screen appears before GRUB.

I forgot to mention that the UUID of the partition it was looking for did not 
exist on-disk after completing the Guix installation process. Given the above 
manpage, I assume this means the crypttab file used in the encryption process 
wasn't fully replaced. Perhaps the file in question is appended to with Guix 
data rather than overwritten? Or perhaps it's not used at all for the way Guix 
does encryption and just gets left behind?

Interesting... I did the full-disk guided installation method, so that should 
have done the trick, then.

This reminds me, I noticed that it didn't rewrite specifically the boot 
partition. When it showed the partition scheme at the end of the partitioning 
stage, it only showed it changing nvme0np2 (and nvme0np3 with encryption 
disabled - it only created swap with encryption disabled), while the boot was 
nvme0np1. After wiping the table, it showed all three.

Hopefully this helps.

Thanks,
Juli
