Once pxe image is booted. The boot.scr file should be able to boot from local file system. kernel and ramdisk address are provided by environment variables set on arm board. Change-Id: I4ad523f85baf488e50a9bc64a926830d4d749195

Installs grub boot loader from packages.
|
||||
|
||||
Set up grub boot loader on the disk using os-refresh-config when system boot
|
||||
up and enables boot from HDD. This needs at least one PXE boot after deployment
|
||||
to work properly.
|
||||
If you want to build an image with localboot for non arm architecture:
|
||||
|
||||
In case Grub serial terminal support is needed, use serial-console element.

|

If you want to build an image with localboot for uboot arm boards:
|
||||
|
||||
* uboot (when set to boot from the disk) looks on the first disk partition
|
||||
for a file named boot.scr in / or /boot. This is a uboot
|
||||
script file, packaged in the special uboot format (like uImage and uInitrd)
|
||||
by the mkimage command, that tells uboot where the kernel and initrd are, and
|
||||
what the kernel boot arguments. This file is created by mkimage command
|
||||
using the flash-kernel script, provided by the u-boot-tools package.
|
||||
|
||||
* The user must provide a uboot script file which contains kernel, initrd and console
|
||||
parameters. This file path is read from an environment variable named
|
||||
UBOOT\_SCRIPT\_FILE\_PATH.
