Force installation of prestage iso when force_install option is
provided through the kernel commandline When there is an existing installation on the subcloud, the kickstart will ensure that it is not overwritten by the prestaged iso. However, when the force_install option is provided via the kernel commandline, the existing installation can be overwritten. Test Plan: PASS: Verify that the prestage iso overwrites the existing installation when the force_install option is provided at the kernel commandline. PASS: Verify that the installation halts with a message, if there is an existing installation and force_install option is not provided at the kernel commandline. PASS: Verify that the prestage iso installs when there is no pre-existing installation and force_install is provided PASS: Verify that above tests pass on NVMe-based systems Regression: PASS: Verify that the prestage iso installs without force_install and no installation exists Story: 2009948 Task: 44914 Signed-off-by: Shrikumar Sharma <shrikumar.sharma@windriver.com> Change-Id: I2491d80cb4e07aa2fb38381c9e92afd7549526ef
