sdt pxe - create linux kernel and initrd images for PXE installer
sdt pxe [options]
The pxe command creates an updated initrd image based on the initrd file contained on the media specified by the -b/--base option with updates applied from the files contained in the directory specified by the -u/--updates option.
In addition, a Linux kernel image will be extracted from either the base media or a kernel package if provided as an update.
The initrd image will be placed the specified output directory as the file initrd. The Linux kernel image will be placed in the same directory as the file linux.
These files can be deployed on a PXE boot server for booting systems using the updated kernel or kernel modules.
To create the PXE boot files use the pxe sub-command of the sdt tool.
sdt -O PXE-files pxe -u updates -b ./distro/sles11sp1-x86_64The -O/--outputdir option of the sdt command specified the location where the PXE files should be placed.
The -b/--base option to points to the distro installation media used as a basis of the bootable driver kit.
The -u/--updatedir option specifies a directory where the sdt tool will find the files to be added to the Update Medium. Any KMPs, kernel packages, or other files found in the directory will be added to the initrd appropriately, and the 'linux file exported will be based on any default flavor kernel package provided. If no updated kernel package is provided, the linux kernel image will be exported from the base media.
Points to the contents of the initial installation media of the SUSE Linux Enterprise Product that the driver kit is designed to work with. Option can point to either a directory containing the contents of the installation media, or the media ISO image itself.
This option will cause the driver kit to be built as a bootable driver kit.
Directory to be scanned for update files to be added to driver kit. Directory will be scanned for kernel packages, KMP packages, YaST2 modules (.ybc), and tar files (.tgz).
Work directory. Created if non-existent and remains after completion. If this option is not specified, temporary directory is created and deleted on exit.
Additional module to add to module.config such that it’s added to initrd and linuxrc considers it while probing hardware. MODSPEC is of the following format:
SECTION:MODULE,DESCR,PARAM,PRE_INST,POST_INST,INITRD,AUTO
If the kernel doesn’t contain any new driver which should be loaded for installation compared to the kernel contained in the base ISO, this option isn’t necessary.
Do not update the kernel modules in the initrd. When updating the initrd, the kernel modules and related files will be copied as-is from the base media to the bootable driverkit initrd.
Specifies steps to perform. STEPS is any combination of u
, p
and f
. u
stands for Unpack, p
for Prepare and f
for Finish. The default is to perform all steps, that is, -s upf
.
Unpack step copies necessary directories and files from base ISO under workdir/boot.staging, unpacks initrd from it under workdir/initrd.staging and kernel package under kernel.staging. module.config is copied to module.config under workdir and –module options are applied.
Prepare step installs the new kernel, modules and kernel package under appropriate staging directories.
Finish step packs the initrd and then produces the ISO.
This option allows manual customization or fix up of media. Note that –workdir must be specified when this option is used.
When scanning the UPDATEDIR for files to be added to the driver kit, certain files will be automatically detected and specific actions taken. See sdt-file-detection (7) for more information on how files are detected.
