Supported Actions

We need to support an extensible set of "actions", which we define as reversible operations that a package can request to enable its later function on the target image.

Packages need a limited set of operations on individual files to manipulate the configuration. The current class actions are given in Appendix A. It appears that if "manifest" and "rbac" were supported, along with some management of editable files (preserve, renamenew, initd, renameold), then the remaining operations could be deferred to image instantiation.

From the legacy packaging system, we can inspect the class action scripts and the postinstall scripts to identify the set of common actions.

depend
Declare dependency on other packages.
directory
All directories.
driver
Package contains device driver Module loading will be disabled during operations on live images.
file
All other files. Preservation and rename handling are managed as optional tags.
hardlink, link
All hard and symbolic links.
service
Package contains service description. Inventoried services will be temporarily disabled during operations on live images.
set
Set a package tag.
user, group
Package requires user, group, or other package-reference managed resource.

XXX Is this set sufficient to boot? Should we somehow discriminate them from non-booting actions?

legacy
Record package attributes into legacy packaging metadata.
license
License files, which deliver into the image metadata rather than the image's filesystems.

XXX Do we have a hard-reboot, reconfigure-reboot, and/or soft-reboot action? Otherwise we are going to build path knowledge somewhere else in the packaging system.

Interface summary:

<interface>
    <action name="dependency" payload="false" commitment="Committed" />
    <action name="directory" payload="false" commitment="Committed" />
    <action name="hardlink" payload="false" commitment="Committed" />
    <action name="legacy" payload="false" commitment="Committed" />
    <action name="license" payload="true" commitment="Committed" />
    <action name="link" payload="false" commitment="Committed" />
    <action name="driver" payload="false" commitment="Committed" />
    <action name="file" payload="true" commitment="Committed" />
    <action name="group" payload="false" commitment="Committed" />
    <action name="service" payload="true" commitment="Committed" />
    <action name="user" payload="false" commitment="Committed" />
</interface>
  1. Custom actions

It is discouraged, but certainly possible to deliver custom actions into the appropriate $PYTHONROOT/vendor-packages/pkg directory, by including those actions in a separate package that the new package requires, and invoking the pkg(1) client twice--once to deliver the custom actions and once to use them to install the new package. (Rescanning pkg.actions would complicate the image plan/package plan evaluations.)

The deployer may wish to deny such actions from operating. For this case, the set of known actions is fixed elsewhere in the pkg modules and updated with subsequent versions. A global and per-image policy, known-actions-only, allows the deployer to disallow operations on packages utilizing actions of unknown provenance.

Interface:

<interface>
    <policy name="known-actions-only" scope="global,image"
        type="boolean" commitment="Committed">
    Deployer control over execution of unknown actions.
    </policy>
<interface>
