Was about to cite TNG Tech Manual as well - although that also said that holodeck characters’ bodies were replicated meat puppets, which I think they didn’t stick with.

If it doesn’t simulate a connected monitor, it looks like there are little HDMI shims that do called EDID emulators that are available for relatively cheap.
(Note: Anything I say could be B.S. I could be completely misunderstanding this.)
Clevis isn’t too difficult to set up - Arch Wiki documents the process really well. I’ve found it works better with dracut that mkinitcpio.
As for PCR registers (which I haven’t set up yet but should), what I can tell, it sets the hash of the boot partition and UEFI settings in the TPM PCR register so it can check for tampering on the unencrypted boot partition and refuse to give the decryption keys if it does. That way, someone can’t doctor your boot partition and say, put the keys on a flash drive - I think they’d have to totally lobotomize your machine’s hardware to do it, which only someone who has both stolen your device and has the means/budget to do that would do.
You do need to make sure these registers are updated every kernel update, or else you’ll have to manually enter the LUKS password the next boot and update it then. I’m wondering if there’s a hook I can set up where every time the boot partition is updated, it updates PCR registers.
JavaScript be like that sometimes…
That is so me sometimes.
You're somewhat right in the sense that the point of disk encryption is not to protect from remote attackers. However, physical access is a bigger problem in some cases (mostly laptops). I don't do it on my desktop because I neither want to reinstall nor do I think someone who randomly breaks in is going to put in the effort to lug it away to their vehicle.
Clevis pretty much does TPM encryption and is in most distros' repos. I use it on my Thinkpad. It would be nice if it had a GUI to set it up; more distros should have this as a default option.
You do have to have an unencrypted boot partition, but the issues with this can at least in be mitigated with PCR registers, which I need to set up.
It’s a smidge more difficult on Debian if you want to use a non-ext4 filesystem - granted for most people, ext4’s probably still fine. I use it on my desktop, which doesn’t have encryption.
Yes, fellow OpenTTD player.
I’m using LVM. The BIOS solution would be a bad idea because it would be more difficult to access the drive on other systems if you had to; LVM allows you to enter your password on other systems to decrypt.
Do your servers have TPM? Clevis might be the way to go; I use it on my Thinkpad and it makes my life easy. If the servers don’t have TPM, Clevis also supports this weird thing called Tang, which from what I can tell basically assures that the servers can only be automatically decrypted on your local network. If Clevis fails, you can have it fall back to letting you enter the LVM password.
Cool. In a little over a month, I hit 3 years.
