13 How to configure a new FreeBSD branch

When a new branch is created, some work needs to be done to specify that the previous branch is no longer equivalent to HEAD. The following instructions apply to the previous branch number:

• Create a new zfs filesystem for sources:

  zfs create a/snap/src-branch
  

  
  
  

• Checkout a src tree in the new filesystem:

  cvs -Rq -d /r/ncvs co -r RELENG-branch
  

  
  
  

• Edit the master copy of Tools/portbuild/portbuild.conf.

• For each arch, edit its copy of the above in /var/portbuild/arch/portbuild.conf.

• Edit /var/portbuild/scripts/buildenv.

• Add a link from /var/portbuild/scripts/dopackages to /var/portbuild/scripts/dopackages.branch.

• Modify HEAD_BRANCH and NON_HEAD_BRANCHES in /var/portbuild/scripts/updatesnap.

• Add the snap directory to /var/portbuild/scripts/zexpire.

• In the /var/portbuild/errorlogs/ directory, create links for the webserver:

  ln -s ../arch/branch/builds/latest/bak/errors arch-branch-full
  ln -s ../arch/branch/builds/latest/bak/logs arch-branch-full-logs
  ln -s ../arch/branch/builds/latest/errors arch-branch-latest
  ln -s ../arch/branch/builds/latest/logs arch-branch-latest-logs
  ln -s ../arch/branch/builds/latest/bak/packages arch-branch-packages-full
  ln -s ../arch/branch/builds/latest/packages arch-branch-packages-latest
  

  
  
  

• Kick-start the build for the branch with

  build create arch branch
  

  
  
  

• Create bindist.tar .
