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 ... _______________________________________________ Help-grub mailing list [email protected] https://lists.gnu.org/mailman/listinfo/help-grub
