If such a command exist, You can read the version from 
your bootcmd, and send it as a parameter.

Yet another alternative:

A command "sync_version"
1) checks if "ver" and 'version' are identical
2) sets "ver" to version, if not the same.
3) saves the environment

With this, the user can select if/when to sync

Ideally this should be in a script "reboot_cmd" which
gets executed at every reboot before anything else
is executed.

Is there such a facility?
