Even if it is only 1000 lines in plan 9, but likely more in FreeBSD and by the way not yet ported to FreeBSD. We know got can't crash the system and is small enough to not matter, even if it isn't in the base today.

News to me. Since there is one repo for /usr/src and /usr/src/sys, this would
mess things up. Why have more or less two identical repos. In the quick hack
script below I assume one. This will need more work, this was just a PoC to
show what I mean. For an existing local repo the script can be enhanced to
fetch to a later commit hash (or one can just use git). 

#!/bin/sh
cmd=`basename $0`
case .$2 in
.) echo Usage: $cmd url commit-hash; exit 1;;
esac
if [ -e .git ]; then echo $cmd: .git already exists; exit 1; fi
# check if there are any other files
if [ ! -z  "$(ls -A)" ] ; then
        echo $cmd: directory must be empty
        exit 1
fi
git init
git remote add origin $1
git fetch --depth=1 origin $2 || exit 1
git checkout FETCH_HEAD
