os-refresh-config

os-refresh-config uses dib-run-parts to run scripts in a pre-defined set of directories:

/opt/stack/os-config-refresh/pre-configure.d
/opt/stack/os-config-refresh/configure.d
/opt/stack/os-config-refresh/migration.d
/opt/stack/os-config-refresh/post-configure.d

/opt/stack/os-config-refresh is the default base directory. You can set OS_REFRESH_CONFIG_BASE_DIR environment variable to override the default one.

Its intended purpose is to separate scripts execution into 4 phases:

  1. Quiesce(pre-configure.d),
  2. Configure(configure.d),
  3. Migrate(migration.d),
  4. Activate(post-configure.d).

It runs through all the phases above to ensure configuration is applied and enabled on a machine. It will exit with an error if any phase has a problem. The scripts in each phase should not depend on each other having worked properly.
