So basically, my setup has everything encrypted except /boot/efi. This means that /boot/grub is encrypted, along with my kernels.

I am now attempting to get secure boot setup, to lock some stuff, down, but I encountered this issue: https://bbs.archlinux.org/viewtopic.php?id=282076

Now I could sign the font files... but I don't want to. Font files and grub config are located under /boot/grub, and therefore encrypted. An attacker doing something like removing my hard drive would not be able to modify them.

I don't want to go through the effort of encrypting font files, does anyone know if there is a version of grub that doesn't do this?

Actually, preferably, I would like a version of grub that doesn't verify ANYTHING. Since everything but grub's efi file is encrypted, it would be so much simpler to only do secure boot for that.

And yes, I do understand there are security benefits to being able to prevent an attacker that has gained some level of running access to do something like replacing your kernel. But I'm less concerned about that vector of attack, I would simply like to make it so that my laptops aren't affected by evil maid attacks, without losing benefits from timeshift or whatnot.

I found the specific commit where grub enforces verification of font files: https://github.com/rhboot/grub2/commit/539662956ad787fffa662720a67c98c217d78128

But I don't really feel interested in creating and maintaining my own fork of grub, and I am wondering if someone has already done that.

    Stooping to insults now, huh?

    Why not write your own bug-free grub then....

    Unironically good advice. Although I would probably just contribute to systemd-boot or refind so that it gets the features I want rather than forking grub, or writing my own bootloader.

    If you think reading about secure boot for 3 weeks is enough for you know everything about the subject, I don't know what to tell you.

    You can never know everything. But you can know enough.

    Besides, you walked in with no knowledge, simply telling me I was wrong. This isn't an actual rebuttal to the points I have brought up.

    You were never worth my salt anyways, go back to whatever dungeon you crawled from. You pathetic vermin.

    I was so "not worth your salt" that you made 6 replies to me. Sounds like you're crying some salty tears. Am I worth that salt?

    To echo your words from earlier in this thread:

    Sounds like cope to me
