Background:
tmt does take so long (30 minutes) to clone the code from https://gitlab.cee.redhat.com/kernel-qe/kernel/-/tree/master/networking?ref_type=heads.

So I create a repository(https://gitlab.cee.redhat.com/kernel-qe/networking/sync_kernel_networking) to sync code from kernel.

I try to write a gitlab-ci.yml in sync_kernel_networking.
```
variables:
OLD_REPO_URL: "https://gitlab.cee.redhat.com/kernel-qe/kernel.git"
SYNC_BRANCH: "master"
NEW_REPO_URL: "https://gitlab.cee.redhat.com/kernel-qe/networking/sync_kernel_networking.git"
default:
artifacts:
expire_in: 1 week

stages:

• sync

workflow:
rules:

• if: '$CI_PIPELINE_SOURCE == "schedule" && $CI_COMMIT_BRANCH == "master"'
• when: never

sync_from_kernel_qe_repo:
stage: sync
before_script:

• export PATH=$HOME/.local/bin:$PATH
• git config --global user.email "mhou@redhat.com"
• git config --global user.name "Minxi Hou"
• mkdir -p ~/.ssh
• echo "$NEW_REPO_SSH_PRIVATE_KEY" | base64 -d > ~/.ssh/id_rsa
• chmod 600 ~/.ssh/id_rsa
• ssh-keyscan -H gitlab.cee.redhat.com >> ~/.ssh/known_hosts
  script:
• git clone --no-tags --single-branch --branch ${SYNC_BRANCH} ${OLD_REPO_URL} old-repo
  echo "Syncing networking directory from old repository"
  pushd old-repo
  echo "Extracting networking subtree..."
  git subtree split --prefix=networking -b networking-sync
  git remote add new-repo ${NEW_REPO_URL}
  git fetch new-repo main || true
  LATEST_REMOTE=$(git rev-parse new-repo/main || echo "")
  LATEST_SUBTREE=$(git rev-parse networking-sync)
  echo "kernel-qe/networking/sync_kernel_networking.git latest: $LATEST_REMOTE"
  echo "kernel-qe/kernel.git latest: $LATEST_SUBTREE"
  if [ "$LATEST_REMOTE" = "$LATEST_SUBTREE" ]; then
  echo "No new networking commits, skipping push."
  else
  echo "New commits detected, pushing..."
  git push new-repo networking-sync:master --force
  fi
  echo "Complete history with original authors has been pushed to the new repository."
  popd
  rm -rf old-repo
  only:

• master
  timeout: 2h

```
