/etc/service-policy.d/*.pol - configuration for policy-rc.d-declarative

Files in the directory /etc/service-policy.d are opened and parsed by the policy-rc.d-declarative script. Lines should have exactly three fields of data which are separated by whitespace; any trailing whitespace is ignored. All files are opened in order by file name; following that, all rules in a file are evaluated in order. The first rule that matches a given service with a given action is applied. All further rules are ignored. If no rule matches a given service with a given action, the default is to exit with exit state 100, which signals "unknown initscript id" to the calling update-rc.d program.

The file contains the following fields: 1. The service(s) to which this should apply. This should be a perl regular expression that matches the init scripts for which this policy should be used. 2. The action(s) which invoke-rc.d wants to take. For more information on the available actions, see /usr/share/doc/init-system-helpers/README.policy-rc.d.gz. 3. The policy to apply to this action. Available policies are: allow Allow the action that invoke-rc.d wants to perform without modification deny Do not allow the action. restart-ignore Replace the action that invoke-rc.d wants to perform by "restart stop". That is, try a restart action first; if that fails for some reason, try a stop action. Note that at the time of this writing, not all PID1 implementations support this. Notably, the systemd version of invoke-rc.d does not support overriding actions.
