summary: Check that gadget.yaml can remove/add kernel command lines
details: |
Gadget snaps have influence over the boot process, and subsequently,
can control the kernel command line - a critical resource in many ways. This
test verifies that an updated gadget snap can effectively add or remove kernel
command line arguments.
