Hello,

Thank you for you work with this script!

I'm almost there but I cannot get my key to be accepted by the remote access setup, if I:

I can login directly to the system using the key without any password so I assume that the key in authorized_keys is properly added.

Some shell output:

Login and update

❯ ssh -i ~/.ssh/my_private_key andre@192.168.1.XX
Enter passphrase for key '<redacted>':

Try to access remote unlock shell

❯ ssh -i ~/.ssh/my_private_key -p 222 user@192.168.1.XX
Welcome to the ZFSBootMenu initramfs shell. Enter "zbm" to start ZFSBootMenu.

What am I missing?

What happens if you connect to the remote unlock shell using: ssh root@192.168.1.XX -p 222 You should be using the root user to connect to the remote shell.
