Because you can only create encrypted home for another not logged in user, you must create a separate user to set up the encrypted home for.

The manjaro_setup_encrypted_home.sh script will set the ecryptfs pam moduls, and encrypt the home dir if the user has no running processes (not logged in).

Follow the original instructions from the encryption output at the end of the process: the target user should test if he/she can log in before the restart.

After setting encrypted home(s), a restart is advised.
