Functions

func FirstBoot

func FirstBoot() error

FirstBoot will do some initial boot setup and then sync the state

func UpdateRevisions

func UpdateRevisions(ovld *overlord.Overlord) error

UpdateRevisions synchronizes the active kernel and OS snap versions with the versions that actually booted. This is needed because a system may install "os=v2" but that fails to boot. The bootloader fallback logic will revert to "os=v1" but on the filesystem snappy still has the "active" version set to "v2" which is misleading. This code will check what kernel/os booted and set those versions active.
