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.
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, rescue mode attaches an existing operating system to the rescue system under the directory `/mnt/sysimage/`.
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.

Booting Your Computer in Rescue Mode
Blacklists (completely disables) one or more drivers. Drivers (mods) disabled using this option will be prevented from loading when the installation starts, and after the installation finishes, the installed system will keep these settings. The blacklisted drivers can then be found in the `/etc/modprobe.d/` directory.
Available Boot Options
Automatic Interface Configuration Methods
|Automatic configuration method|Value
|IPv6 DHCP|`dhcp6`
|IPv6 automatic configuration|`auto6`
|iBFT (iSCSI Boot Firmware Table)|`ibft`
A system installed using `VNC` will start in text mode by default.
Assigns a given interface name to a network device with a given MAC address. Can be used multiple times. The syntax is [option]#ifname=pass:attributes[{blank}]_interface_:pass:attributes[{blank}]_MAC_pass:attributes[{blank}]#. For example:
[application]*Memtest86+* only works on systems with BIOS firmware. Support for UEFI systems is currently unavailable.
an ISO image of the full {PRODUCT} installation DVD, placed on a hard drive or a network location accessible from the installation system
an installable tree, which is a directory structure containing the installation program's images, packages and repodata as well as a valid `.treeinfo` file
Allows you to run the installation in single language mode - in other words, this option disables language selection for the installer and the installed system. If you also use the [option]#inst.lang=# option at the same time, the language you specify will be used. If you do not set the language, [application]*Anaconda* and the installed system will default to `en-US.UTF-8`.
Allowed you to debug the loader. Use [option]#rd.debug# instead.
`all_ks` - disables saving of both input and output Kickstart files.
