btrfs-todo VS mortar

It should be resolved with "Tree extension V2" https://github.com/btrfs/btrfs-todo/issues/25

You could open a feature request at https://github.com/btrfs/btrfs-todo/.

Thankfully, much of the work with extent tree v2 will address most of these issues, so expect this to improve in the next year or two.

Pretty sure that will become possible/easier with Extent tree v2.

fscrypt support for btrfs is still being planned; see the most recent comments at https://github.com/btrfs/btrfs-todo/issues/25

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:

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
