  • The TPM releases the key to the OS at boot time. Without that, there would be no way for the OS to load (assuming the root FS is encrypted).

    The key is bound to PCRs in the TPM, which control under what conditions the key can be released. For example, it can be tied to secure boot, bios settings, etc.





  • With rootless containers, even root in the container is basically useless anyway because it truly runs as a fake ID on the host.

    I’ve seen this repeated a lot, but I’m not really convinced running as root inside containers is a good/safe thing to do. User namespaces can provide some protection for the host, but that does nothing for the rest of the files inside the guest. For example, consider a server software with an arbitrary file write vulnerability. If the process is running as a low privilege user, exploiting the vulnerability might not really get you anywhere. If it’s running as root, it’s basically a free pass to root privilege and arbitrary code execution within the container.

    You could maybe do some tricks with one of the variations of locate - such as mlocate or locate. There are options for the updatedb to index specific paths and store in the specified database. If you store a separate db per drive, a bit of scripting to loop through all DBs would let you search them all.
