Thanks for filing an issue with Oracle Linux.

GitHub Issues is not an official support channel and we don't offer

[AmedeeBulle]

@YoderExMachina this is a valid request for the scripts posted in this repo

[AmedeeBulle]

@nkm269 , can you post the diffs rather than a big chunk of code?
It is not clear to me what you changed and what you are trying to achieve

[YoderExMachina]

This is the standard reply agreed upon by Oracle Linux Management (@gregmarsden). As the statement reads, if we consider this a bug, we will open an internal ticket and pursue a fix, however in this case I am reluctant to do so as the script has been modified from the version we provided. Please let me know if you believe this is still a bug.

other than that i didnt do any change

[AmedeeBulle]

Changing BOOT_MODE, ROOT_FS, SETUP_SWAP (or any other variable) in the kickstart template won't work, because these variables are driven by their (inherited) values from the env.properties files and are used elsewhere in the scripts as well.
(You can see the final properties and kickstart files in your build directory)

You need to define these in your env.properties

I also see that you have an hard-coded disk size in your parted:

  parted -s -a optimal /dev/${DISK}  mkpart pv_vol ${start}MiB 50GB

This is inconsistent with the allocated disk size of 15GB

 Allocating 'OL8U10_x86_64-oci-b0.qcow2' | 15 GB 00:00:00

Disk image size is derived from the DISK_SIZE_GB parameter:

oracle-linux/oracle-linux-image-tools/env.properties

Lines 130 to 131 in de7d51a

	# Allocated disk size for the image, default is distribution / cloud specific
	# DISK_SIZE_GB=

Unless you do not want to allocate the full (virtual) disk, you better keep using 100% in the kickstart file as it was; it will avoid loosing space or over-committing.

If it still doesn't work after making the above changes, please provide:

• your env.properties file
• the output of git diff to show your exact changes

Note: setting the SERIAL_CONSOLE property to yes can be useful to detect issues during kickstart processing.

[nkm269]

great it worked after increasing the size. one more question
how to add packages ? i addedd packages under this

added repo

repo --name=ol8-addons --baseurl=https://yum.oracle.com/repo/OracleLinux/OL8/addons/x86_64

oracle-linux/oracle-linux-image-tools/distr/ol8-slim/ol8-ks.cfg

Line 135 in de7d51a

%packages

xorg-x11-utils
binutils-2.30-49.0.2.el8
make-4.2.1-9.el8

it failed with same error.once i remove it, it works fine.

[AmedeeBulle]

You should stay away of the kickstart file as much as possible as it will cause issues that are difficult to diagnose.

The recommended way is to create an entry in the custom directory -- see Customizing builds in the README file, in particular the custom::provision() hook is the place where you can easily install packages (take the template subdirectory as example).

To enable your custom hooks, set CUSTOM=<name of your subdirectory> in your properties file (I am afraid I forgot to mention that in the README 😊 )

[nkm269]

thank you @AmedeeBulle . you are very helpful.
