README

Services declared as oneshot are expected to take some action and exit immediatelly (thus, they are not really services, no running processes remain). A common pattern for these type of service is to be defined by a setup and a teardown action.

Define setup/teardown actions

Create executable file /opt/foo/setup-foo.sh:
