If the later opts override the earlier (I think they do), then we should put opts after rematch here, because the user explicitly added those options to the command line, and therefore probably prefers them. > elif [[ $line =~ ^groups\ *=\ *(.*)$ ]]; then > groups=${BASH_REMATCH[1]} > elif [[ $line =~ ^arch\ *=\ *(.*)$ ]]; then > -- > 2.11.0 > Thanks for this patch! I'm looking forward to making use of it for testing Peter's EL2 series with/without "-machine virtualization=on" drew _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
