exactly, u-d-f creates an image and then installs the kernel snap
inside. after it installed it knows the exact path to the binaries,
which is /snap/$packagename/$revision and this path is set to
snappy_kernel= inside the uboot.env file. every time you upgrade or
roll-back the kernel this variable is adjusted alongside, if a boot
fails the value automatically falls back to the last revision that
worked and it reboots.
