在哪裡送出新的 mimetypes？

我已經用文件後綴定義了新的 mimetypes，我應該在哪裡送出我的工作，以便它將包含在未來的 linux/unix 發行版中？

我的 /etc/mime.types 以：

# This file maps Internet media types to unique file extension(s). It is
# distributed in Arch Linux as the mime-types package, which is based on
# Gentoo's app-misc/mime-types package.
#
# The table below contains both registered and (common) unregistered types.
# A type that has no unique extension can be ignored -- they are listed
# here to guide configurations toward known types and to make it easier to
# identify "new" types. File extensions are also commonly used to indicate
# content languages and encodings, so choose them carefully.
#
# Internet media types should be registered as described in RFC 4288.
# The registry is at <http://www.iana.org/assignments/media-types/>.
