@andi:kack.itandi-Ok, I actually think Fedora has done that stuff. There is that dracut plugin that allows you to do SSS, Password, remote unlock and TPM based unlock etc..13:57:58
@grahamc:nixos.org@grahamc:nixos.orgalthough in what I've set up here I get PCR validation and encrypted disks without using nvram statue13:58:02

@grahamc:nixos.org@grahamc:nixos.orgso it would only get wiped if they switched to windows and windows cleared the tpm13:58:31
@andi:kack.itandi-https://aboutcher.co.uk/2020/06/fedora-linux-luks-encryption-with-tpm-unlock/ this sounds so easy :D14:02:06
@hexa:lossy.networkhexaoh right, clevis.14:02:51
@andi:kack.itandi-Getting clevis to work on NixOS would already be amazing. SSS for unlocking a community computer is a common enough use case.14:03:33
@hexa:lossy.networkhexaright, that's when we looked into that14:03:59
@andi:kack.itandi-and tango is the remote attestation part to it14:05:09
@grahamc:nixos.org@grahamc:nixos.orgI clicked the link thinking "oh great, exactly what we need, yet another blog post with some obscure commands with dozens of flags that probably makes it work just barely well enough but not actually be thorough"14:08:15
@grahamc:nixos.org@grahamc:nixos.orgbut it is short enough that I reasonably trust it!14:08:23
@andi:kack.itandi-So clevis probably puts the two public parts into the initrd?14:09:15
