Description Keigo Noha 2023-12-22 08:45:16 UTC 
Description of problem:
tripleo_kernel_args is not applied when the new KernelArgs is subset of preceding one. 

Let me assume that the following situation.

1st deployment with KernelArgs: "isolcpus=1,3,5,7,9,11,13,15"
2nd deployment with KernelArgs: "isolcpus=1,3,5,7,9"

At the 1st command, KernelArgs was successfully applied.
At the 2nd deployment, the new KernelArgs option is not reflected to /etc/default/grub. 


Version-Release number of selected component (if applicable):
OSP17.1

How reproducible:
Always.

Steps to Reproduce:
1. Deploy with KernelArgs
2. Then run small changes in KernelArgs which just reduce the core number of KernelArgs

Actual results:
The assigned KernelArgs is not applied to /etc/default/grub.

Expected results:
The modification to KernelAargs are always affected.
