freezer-scheduler without api service
freezer-scheduler without api service

Add the ability to start the freezer-scheduler without any
OS identity variable when used with the parameter

  --no-api

In that case the scheduler loads the configuration files for
the jobs from local files with the extension .conf located
in the directory

  /etc/freezer/scheduler/conf.d

The default path can be changed using the parameter

  --conf
