mortar VS TrustedGRUB2

Bruteforce of such random password is just not plausible and talks about KDF "weakness" is just a distraction. I think most likely it was evil maid attack.

Here are projects which try to mitigate some of evil maid attack risks:

https://safeboot.dev/

Secure boot and TPM support (à la Mortar: https://github.com/noahbliss/mortar)

There are tools that look to be able to automate it: https://github.com/noahbliss/mortar/blob/master/docs/proxmox-install.md

I just went through the process of setting up new ubuntu VM's using full root disk LUKS encryption and auto-unlock via Proxmox's vTPM2.0 and UEFI ( via this extremely helpful resource https://github.com/noahbliss/mortar )

I have used this project with Debian+proxmox and it's been working great. https://github.com/noahbliss/mortar but I did read the arch wiki a bit which helped my understanding.

There's a project called "mortar" (as in, gluing all these bricks together) that was attempting to simplify this. Though it's lost steam, reading through it's simple bash scripts was a great place to start for me. This guide for Fedora also helped a lot.

There have been a number of attempts to solve this problem, but the most complete appear to be Mortar (a project I head) and safeboot.dev

I highly recommend taking a look at either of these projects if you want be able to improve both your convenience through auto unlocking, and security through broadened scope of audit.

Check out mortar. It uses secure boot and TPM along with LUKS. The creator is super helpful and available on the telegram.

A more advanced approach would be something like mortar to chain-load signed stuff.

There seems to be a workable solution out there for 2.0: https://github.com/noahbliss/mortar/blob/master/docs/proxmox-install.md

Last time I checked, yes. There's been a few projects like TrustedGRUB2 *(which luks-tpm-boot uses) that was intended to make this work on GRUB. But in all fairness, GRUB is pretty dead to me personally as it's a lot of workarounds depending on what hardware you're working with. The only reason really we support GRUB is because it works on older hardware and on more edge cases (like USB drives etc). But if I could choose, I'd make it so everyone used EFI and we could use systemd-boot everywhere ^

AFAIK trusted boot is in limbo, the upstream project is no longer maintained and it was never very clear exactly how it should be exposed to users anyway. So yeah it has been removed from TW.

Trusted Boot in yast2 switches the bootloader to TrustedGrub2 instead of normal Grub2. It does work on both legacy bios and EFI. This adds several verification steps to the boot process but be aware the support is somewhat piecemeal. I am not an expert on the details.
