[22:48] Hi all I am playing around with Cloud-Init with Vagrant for Ubuntu 2004 and was wondering would I be able to set a Hostname via Enviromnet Variables with the placehoder in the user-data.yml file? [22:49] I tried adding a `${NEW_USER}` into the `user-data.yml` but on the vagrant image i do not see any substitution. I see a user literally created like ${NEW_USER} and no substituion
