✅ There is something you can do right away to help this project succeed! **Just take a few minutes to send a support request to Hetzner, asking them to please add openSUSE MicroOS as a default image**, not just an ISO. If that succeeds, we will be able to deploy in less than 2 minutes instead of 5, without passing by the rescue mode. The more requests they receive the likelier they are to add it. The official link to openSUSE MicroOS is <https://get.opensuse.org/microos>. 🌱 There is something you can do right away to help this project succeed! **Just take a few minutes to send a support request to Hetzner, asking them to please add openSUSE MicroOS as a default image**, not just an ISO.
