## Install tarball

### clean known_host doesnt work

### install from tarball example:

```yaml
- name: "If jdk not exists then only download and unarchive"
  unarchive:
    src: "https://download.oracle.com/java/17/latest/jdk-17_linux-aarch64_bin.tar.gz"
    dest: /opt/
    remote_src: yes
    creates: /opt/jdk-17
  register: foo
- name: "Rename if download happens "
  command: mv /opt/jdk-17_linux-arch64 /opt/jdk-17
  when: foo.changed == True
```

### configure DNS record for newly created instance

https://github.com/bodsch/ansible-collection-dns/blob/main/roles/knot/README.md

or using e3 using wrapper script around `jaildk exec dns knotc ...`

### Cleanup release snapshot

- remove pkg function from root .bashrc

## fix home mount

nullfs into jail

## Add users with authorized_keys files

## Add quota config and enable/configure rctl

## DNS

- kresd.conf => listen on ::
- add ::1 to host resolv.conf
- add default gw to jail resolv.conf

## Network

- {{ ansible_default_ipv6.interface }} sometimes resolves to the link local ip, not the inet6 one, which results in a wrong (or none) default route and resolve.conf inside the jail.
