| 2 | GUID definition for the Linux Initrd media device path
|
|---|
| 3 |
|

| 4 | Linux distro boot generally relies on an initial ramdisk (initrd) which is
|
|---|
| 5 | provided by the loader, and which contains additional kernel modules (for
|
|---|
| 6 | storage and network, for instance), and the initial user space startup code,
|
|---|
| 7 | i.e., the code which brings up the user space side of the entire OS.
|
|---|
| 8 |
|
|---|
| 9 | In order to provide a standard method to locate this initrd, the GUID defined
|
|---|
| 10 | in this file is used to describe the device path for a LoadFile2 Protocol
|
|---|
| 11 | instance that is responsible for loading the initrd file.
|
|---|
| 12 |
|
|---|
| 13 | The kernel EFI Stub will locate and use this instance to load the initrd,
|
|---|
| 14 | therefore the firmware/loader should install an instance of this to load the
|
|---|
| 15 | relevant initrd.
