After some investigation, It looks like if there is an update available for mintupdate-tool itself, mintupdate-tool ignores all other available updates and only upgrades itself, regardless of what parameters are provided. The second time it's run, it will actually install other updates. This means we need to fix the install script to call mintupgrade-tool twice or our systems will be going out to users without the latest kernel updates.
