This was posted on Fedora Magazine. It shows how to decrypt a hard drive encrypted with LUKS using TPM2. This allows for Fedora installs and perhaps other Linux installs to setup the TPM to automatically decrypt the hard drive. This would allow a Linux install to boot without the need for entering the encryption password, in the same way that Windows just boots on an encrypted volume.

I have not tried this yet, but am hoping that it works. It would save typing in a password when starting up the machine.
