I followed the guide for avoiding typing the password twice during boot. But I’m still getting asked to type the password for my home drive? So I tried to edit my crypttab file, albeit I don’t understand it fully. My crpyttab is like this:
OK, your setup does not use passphrases at all, so it is irrelevant.
Just generate additional key for cr_home, store it somewhere (e.g. /.home.key) and add to /etc/crypttab. Follow the same unknown guide you followed except you do not need to add the key for cr_home to initrd because it will be unlocked after initrd is finished.
