Autoinstall cloud-init wount run Late-comandows

[eura]

Using Ubuntu Server 22.04, I am attempting to create an auto-installation setup for a physical client. I want to enable root login and execute late commands. Additionally, I want the hostname to be set as "new-client-macadress" without colons. Despite trying various syntaxes, the commands do not seem to take effect. I have experimented with different configurations, but none have yielded the desired results.

Here is my cloud-init conf

- echo "PermitRootLogin yes" | tee -a /target/etc/ssh/sshd_config"
- systemctl restart ssh
