files.kern not included in release source?

[Stephan <stephanwib%googlemail.com@localhost>]

Hi folks,

to me it looks like files.kern in sys/kern is not included in the
source tarballs of stable releases (e.g. netbsd-7). It is only visible
in CVS under the MAIN tag.

I´d like to continue some development based on the stable-7 source, so
I would expect files.kern to be there in order to include my files for
the build.

How can I do that?

Thanks!
