KickstartScriptRevisioning

Adding revisioning to kickstart pre/post scripts

Rational

Allow Spacewalk/RHN Satellite admins to view previous kickstart pre/post script contents. Ideally this would give similar functionality to that provided by the managed config files.

Requirements

• Not block out other potential features (i.e. re-ordering of pre/post scripts)

• Have minimal impact on other Spacewalk/RHN Satellite sub-systems (think API calls)

Nice to have features

• Be able to use macros, a la managed config files.

High level events

Create script

• Pretty much un-changed from now (except for table layouts).

Update script

• A new row should be created for each edit but the 'created' column should be the same as the that of the original copy of the script.

Delete script

• A delete of the script should result in all copies of the script being deleted.

Delete script revision

• Should only delete that script revision, nothing more.
