Comment 14 for bug 1579767

The snappy_* vars would be similar to this ones:

snappy_boot=if test "${snappy_mode}" = "try"; then if test "${snappy_trial_boot}" = "1"; then setenv snappy_os "${snappy_good_os}"; setenv snappy_kernel "${snappy_good_kernel}"; saveenv; else setenv snappy_trial_boot 1; saveenv; fi; fi; run loadfiles; setenv mmcroot "/dev/disk/by-label/writable ${snappy_cmdline} snappy_os=${snappy_os} snappy_kernel=${snappy_kernel}"; run mmcargs; bootz ${loadaddr} ${initrd_addr}:${initrd_size} 0x100
snappy_cmdline=net.ifnames=0 init=/lib/systemd/systemd ro panic=-1 fixrtc
snappy_mode=regular
snappy_trial_boot=0

snappy_ab=a would not be relevant as this is UC16
