#     scripts: merge_config: add strict mode to fail upon any redefinition
#     
#     When merging configuration fragments, it might be of interest to
#     identify mismatches (redefinitions) programmatically. Hence add the
#     option -s (strict mode) to instruct merge_config.sh to bail out in
#     case any redefinition has been detected.
#     
#     With strict mode, warnings are emitted as before, but the script
#     terminates with rc=1. If -y is set to define "builtin having
#     precedence over modules", fragments are still allowed to set =m (while
#     the base config has =y). Strict mode will tolerate that as demotions
#     from =y to =m are ignored when setting -y.
