Hi Stefan, what about a 'scrubenv' or 'cleanenv' command that tries to unset all variables leaving readonlys untouched.
The command could request a confirmation: => scrubenv Do you really want to do this ('yes' or 'no')? yes Can't overwrite "serial#" Can't overwrite "ethaddr" => saveenv The above output is faked. So I did not start coding :-) What do you think?
