arch-specific hooks appended to its end (currently: i386 and amd64). Handle this case in postinstall(8) by checking whether we are in $SOURCEMODE or not, and generate the correct rc.conf file on the fly in case we have to. Otherwise, postinstall(8) may install the default one obtained from a source directory that does not have the MD hooks appended to it. Problem reported by wiz@. Thanks!
