# All Rex file operations now work without SFTP:
file '/etc/hostname', content => "myhost\n";
delete_lines_matching '/etc/fstab', matching => qr/\sswap\s/;
host_entry 'myhost.internal', ip => '127.0.1.1', aliases => ['myhost'];
```

Authentication:
```perl
Rex::Config->set_private_key('/root/.ssh/id_ed25519');
Rex::Config->set_public_key('/root/.ssh/id_ed25519.pub');
```

Host key checking is disabled by default (`strict_hostkeycheck => 0`).
