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.

What makes TPM+pin safer than just having a normal LUKS password? I would think it would be the same amount of security just with more chance of data loss if your computer gets damaged
TPM is used for measured boot. Measured boot can check various parts of the system to ensure they are the expected values haven’t been tampered with. You don’t want a part of the system to be replaced with malware and not realize it.
If it detects something changed, it won’t release its secret. It may signal to you that something malicious was done or something benign that the OS updated didn’t account for.
Interesting, how do you recover from that and get your data back?
A recovery code. I did a test install of Aeon and was given the code: dhnhlgc-fbndjbni-ufrkcfnk-nfebvtut-ftkkiiur-tijidtub-hujnucgu-erduhije
64 digits, but only alphabetical and a certain subset (16/26) due to weirdness of keyboard layouts.
