Use dracut to generate initramfs - #2833

tpm2-unlock.sh wasn't working for me using Ubuntu 26.04. After the reboot the initramfs could not be loaded and the device started a busybox shell. After using dracut instead of update-initramfs as described [here](https://ubuntu.com/server/docs/how-to/security/tpm-backed-luks-decryption-with-clevis/) it worked.

Hi, I am not sure if this will continue to work on Ubuntu 24.04. Maybe we should use dracut on 26.04 and update-initramfs on ubuntu 24.04. WDYT @pq2?

I'm not entirely sure about that either. While clevis-dracut is available in the repositories for 24.04 (Source), dracut doesn't seem to be the default tool for creating the initramfs in 24.04. It can't hurt to use both, depending on the version, as you suggested.
