Would be nice to have the posibillity for "online upgrades".
Select available versions,
download image in sha,
Storing the config with every version, so switching between several version is just a boot away. Would make support much nicer, also there will be some kind of config versioning.Rollbacks are more comfortable. A list below the "Upgrade" with custom comments would make it perfect. Perhaps I sometimes expect to much, but as long there are so many hackers available why not trying to push as much as possible :)
