Moved the thread here. Great idea, but best seen in the Linux forum.
My own contribution.
I have my Framework 13’s system configuration based on flake here. It enables impermanence + Secure Boot + TPM Unlocking LUKS on top of LVM and BTRFS. I daily drive this with multiple systems and try to keep it as simple or straightforward as possible. Would be happy to help anyone else get set up with similar configuration.
