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

/etc/service-policy.d/*.pol

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 the action that invoke-rc.d wants to perform without modification
Do not allow the action.
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.
