It does not work at all, preconfig or not preconfig. You could try to
preload tr module and use

tr --set pretty_mac - : $net_default_mac

although I'm not sure how it will handle lone `-' (argument parsing); probably

tr --set pretty_mac x- x: $net_default_mac

is more foolproof.

Of course all notes about lack of conditional error handling at this
stage still apply ...
