From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I don't know why I keep hearing of security measures to stop someone sleuthing into bootloaders.
Am I the only person using Linux who isn't James Bond?

so you never caught a team of government officials in your living room brute forcing your bootloader at 4am as you got up to use the bathroom, huh. Lucky guy.
I'm still on the hunt for a desktop Linux distro that has no security features or passwords. My usage for this may not be common but it can't be rare enough that there are zero options
Ubuntu, no encryption, select boot to desktop by default when the system installs.
Like, really?
I’m an engineer with trade secrets on his laptop. I’ve heard of dozens of people getting laptops stolen from their cars that they left for like ten or fifteen minutes.
The chances are slims, but if it happens I’m in deep trouble whether those secrets leak of not. I’m not taking the risk. I’m encrypting my disk.
It’s not like there’s a difference in performance nowadays.
TPM's not going to help with that situation, though, right? Either you're typing in your encryption password on boot (in which case you don't need TPM to keep your password), or you're not, in which case the thief has your TPM module with the password in it.
This is why I keep my initrd tattooed as a barcode on my testicles.
"Please teabag the web cam to boot."
Kernel upgrades are very... Painful.
There's two types of users, those who write a detailed precise technical answer to the subject, and then there's you
You know, I've been thinking about what I want my first tattoo to be for months, you've just given me a great idea
TPM bad, put your secrets on a proper encryption peripheral, like a smartcard running javacardOS
TPM will turn into cpu-bound DRM, the more you use it, the more this cancer will grow

You are only seeing what TPM is now. Not what TPM will become when it become an entire encrypted computing processor capable of executing any code while inspection is impossible.
Imagine denuvo running at ring level -1

Trusting some obscure hardware might be a bad idea then.
