This option allows for the configuration of different installation methods using different formats. The syntax is described in the table below.
Installation Sources
|Installation source|Option format
|Any CD/DVD drive|[option]#inst.repo=cdrom#
|Specific CD/DVD drive|[option]#inst.repo=cdrom:pass:attributes[{blank}]_device_pass:attributes[{blank}]#
|Hard Drive|[option]#inst.repo=hd:pass:attributes[{blank}]_device_:/pass:attributes[{blank}]_path_pass:attributes[{blank}]#
|HTTP Server|[option]#inst.repo=http://pass:attributes[{blank}]_host_pass:attributes[{blank}]/pass:attributes[{blank}]_path_pass:attributes[{blank}]#
|HTTPS Server|[option]#inst.repo=https://pass:attributes[{blank}]_host_pass:attributes[{blank}]/pass:attributes[{blank}]_path_pass:attributes[{blank}]#
|FTP Server|[option]#inst.repo=ftp://pass:attributes[{blank}]_username_:pass:attributes[{blank}]_password_pass:attributes[{blank}]@pass:attributes[{blank}]_host_pass:attributes[{blank}]/pass:attributes[{blank}]_path_pass:attributes[{blank}]#
|NFS Server|[option]#inst.repo=nfs:[pass:attributes[{blank}]_options_:]pass:attributes[{blank}]_server_:/pass:attributes[{blank}]_path_pass:attributes[{blank}]#
footnote:[This option uses NFS protocol version 3 by default. To use a different version, add [option]#+nfsvers=pass:attributes[{blank}]_X_pass:attributes[{blank}]# to _options_.]
Disk device names may be specified using the following formats:
Kernel device name, for example `/dev/sda1` or `sdb2`
File system label, for example `LABEL=Flash` or `LABEL=RHEL7`
File system UUID, for example `UUID=8176c7bf-04ff-403a-a832-9557f94e61db`
Non-alphanumeric characters must be represented as `\xpass:attributes[{blank}]_NN_pass:attributes[{blank}]`, where _NN_ is the hexadecimal representation of the character. For example, `\x20` is a white space ("").
Specifies the location of the installation program runtime image to be loaded. The syntax is the same as in xref:Boot_Options.adoc#tabl-boot-options-sources[Installation Sources]. This option expects a path to a directory containing a valid `.treeinfo` file; the location of the runtime image will be read from this file if found. If a `.treeinfo` file is not available, [application]*Anaconda* will try to load the image from `LiveOS/squashfs.img`.
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.
With this boot option, the stage 2 image will be fetched from HTTP, HTTPS and FTP locations which are specified using the [option]#inst.stage2=# option sequentially in the order they are specified, until the image is successfully fetched. All other locations will be ignored.
If you need to perform a driver update during the installation, use the [option]#inst.dd=# option. It can be used multiple times. The location of a driver RPM package can be specified using any of the formats described in xref:Boot_Options.adoc#tabl-boot-options-sources[Installation Sources]. With the exception of the [option]#inst.dd=cdrom# option, the device name must always be specified. For example:
Using this option without any parameters (only as [option]#inst.dd#) will prompt the installation program to ask you for a driver update disk with an interactive menu.
You should never attempt to perform a driver update during the installation unless a missing our faulty driver is preventing you from completing the installation. Updating drivers which are not essential during the installation should always be performed after the system is installed.
Prevents the installer from trying to automatically configure an installation source.
