# 1. fetch the current level of k8s.io/kubernetes
|
|
# 2. check out the k8s.io/kubernetes HEAD into a separate branch
|
|
# 3. rewrite the history on that branch to *only* include staging/src/k8s.io/apimachinery
|
|
# 4. locate all commits between the last time we sync'ed and now
|
|
# 5. switch back to the starting branch
|
|
# 6. for each commit, cherry-pick it (which will keep authorship) into current branch
|
|
# 7. update metadata files indicating which commits we've sync'ed to
