The issue with installing the kernel-image to both rootfs
and boot partition is that some systems rely on the kernel-image in
rootfs and not in the boot partition.
This leads to duplication of the kernel-image, which can cause
unnecessary storage usage and potential compatibility issues.
This patch provides a solution to this problem by adding a new
parameter "skip-kernel-install" to the wic kickstart file, which can
be passed to the plugin.
If the parameter is provided, the plugin will skip installing the
kernel-image to the boot partition, avoiding duplication and potential
issues.
By adding this new parameter, we give the users the option to install
the kernel-image only in rootfs, or to install it in both rootfs and
boot partition, depending on their needs and preferences.
This will help to improve the system's storage usage and compatibility.
Tests for this functionality will be added in the next patch.
