Boot Options
Boot options specific to the installation program always start with `inst.` in this guide. Currently, this prefix is optional - for example, [option]#resolution=1024x768# will work exactly the same as [option]#inst.resolution=1024x768#. However, it is expected that the `inst.` prefix will be mandatory in future releases.
By default, rescue mode attaches an existing operating system to the rescue system under the directory `/mnt/sysimage/`.
By default, swap on zRAM is enabled on systems with 2 GB or less RAM, and disabled on systems with more than 2 GB of memory. You can use this option to change this behavior - on a system with more than 2 GB RAM, use [option]#inst.zram=1# to enable it, and on systems with 2 GB or less memory, use [option]#inst.zram=0# to disable this feature.
By default, this boot option is used on the installation media and set to a specific label (for example, [option]#inst.stage2=hd:LABEL=F21\x20Server.x86_64#). If you modify the default label of the file system containing the runtime image, you must also edit this option to match the new label.
|Configuration Method|Option format
|Automatic configuration of any interface|[option]#ip=pass:attributes[{blank}]_method_pass:attributes[{blank}]#
|Automatic configuration of a specific interface|[option]#ip=pass:attributes[{blank}]_interface_:pass:attributes[{blank}]_method_pass:attributes[{blank}]#
|Static configuration|[option]#ip=pass:attributes[{blank}]_ip_::pass:attributes[{blank}]_gateway_:pass:attributes[{blank}]_netmask_:pass:attributes[{blank}]_hostname_:pass:attributes[{blank}]_interface_:none#
|Automatic configuration of a specific interface with an override
footnote:[Brings up the specified interface using the specified method of automatic configuration, such as `dhcp`, but overrides the automatically obtained IP address, gateway, netmask, hostname or other specified parameter. All parameters are optional; only specify the ones you wish to override and automatically obtained values will be used for the others.]|[option]#ip=pass:attributes[{blank}]_ip_::pass:attributes[{blank}]_gateway_:pass:attributes[{blank}]_netmask_:pass:attributes[{blank}]_hostname_:pass:attributes[{blank}]_interface_:pass:attributes[{blank}]_method_:pass:attributes[{blank}]_mtu_pass:attributes[{blank}]#
Configured a remote display. Replaced with the [option]#inst.vnc# option.
Configured the Domain Name Server (DNS). Use the [option]#nameserver=# option instead.
Configured the installation method. Use the [option]#inst.repo=# option instead.
Configured wireless network access. Network configuration is now being handled by [application]*dracut*, which does not support wireless networking, rendering these options useless.
Configures geolocation usage in the installation program. Geolocation is used to pre-set the language and time zone, and uses the following syntax: [option]#inst.geoloc=pass:attributes[{blank}]_value_pass:attributes[{blank}]#
Configures one or more network interfaces. To configure multiple interfaces, use the `ip` option multiple times - once for each interface. If multiple interfaces are configured, you must specify a primary boot interface using the [option]#bootdev# option described below.
Configure the system for multilib packages (that is, to allow installing 32-bit packages on a 64-bit x86 system) and install packages specified in this section as such.
Configuring the Installation System at the Boot Menu
Connect to a listening `VNC` client at a specified host and port once the installation starts. The correct syntax is [option]#inst.vncconnect=pass:attributes[{blank}]_host_:pass:attributes[{blank}]_port_pass:attributes[{blank}]#. The _port_ parameter is optional - if you do not specify one, the installation program will use `5900`.
