    base-files: uci-defaults: migrate time zonename on upgrade
    
    Timezone names no longer allow spaces, so older installations
    upgrading to new will have their timezone reset to UTC.
    
    For example, on 24.10:
      $ uci get system. at system[0].zonename
      America/Los Angeles
    
    After upgrade to 25.12:
      $ uci get system. at system[0].zonename
      UTC
    
    Add a migration script to edit zonename on first boot.
