Boot options

Agama Live ISO behavior can be altered using the kernel command line at boot time. For those architectures that support Grub, you need to modify the agama-installer entry adding the boot options at the end of the linux line.

It may be easier

We must admit that it is not as convenient as it was when using Linuxrc and YaST. However, we rely on dracut now that it is easier to extend.

agama.auto: Tells the installer to use the profile in the given URL to start an unattended installation.
```
agama.auto=http://mydomain.org/tumbleweed.jsonnet
```
agama.config_url: it uses the file at the given URL as the new Agama configuration. Please, do not confuse this file with an unattended installation profile. See URL handling in the installer to find more details about the supported URLs.
```
agama.config_url=http://192.168.122.1/my-agama.yaml
agama.config_url=usb:///agama.yaml
```
agama.install_url Override the default installation_url set in the product files here by passing the agama.install_url parameter as a boot option in the bootloader. This is particularly useful for any pre-production testing in openQA.
```
agama.install_url=https://myrepo,https://myrepo2
```
warning
Setting this variable will impact all products.
live.password and live.password_hash Set the root password of the live system. live.password accepts a plain text password, while live.password_hash is expected to receive a hashed password, which is more secure. The disadvantage of a hashed password is that it is quite long and is not easy to type it into the boot prompt manually. It makes sense in environments where you can prepare the boot parameters in advance like in PXE boot or some virtual machines.
```
live.password=nots3cr3t
```
Setting a password enables SSH
The SSH service is not started unless a password is provided using any of the available options (live.password, live.password_hash, live.password_dialog, or live.password_systemd). This avoids accidentally using the default password from the medium.
live.password_dialog Start an interactive dialog during the boot process. This uses a nice dialog for entering and confirming the password. However, in some situations the full screen dialog might not be displayed correctly or some messages might be displayed over it. In that case you might use the Ctrl+L key shortcut to refresh the screen. If it still does not work then try using the other option below.
```
live.password_dialog
live.password_dialog=1
```
live.password_systemd Ask for a password using a simple prompt. This is similar to the option above, but the advantage is that this solution does not use a full screen dialog but a single line prompt so it should work better in special environments like a serial console.
```
live.password_systemd
live.password_systemd=1
```
proxy: sets up a network proxy. The supported proxy URL format is protocol://[user[:password]@]host[:port].
```
proxy=http://192.168.122.1:3128
```

Technical tip

When the installation system boots, the agama-proxy-setup service will read the proxy URL to be used from the kernel command line options or through the dracut ask prompt configuration file writing it to the /etc/sysconfig/proxy. After that the microOS Tools setup-systemd-proxy-env systemd service will make the proxy variables from that file available to all the systemd units writing a systemd config file with all the variables as Environment ones.
