Lubomír Sedlář ac66c3d7f3 createiso: Allow reusing old images
This patch allows Pungi to reuse ISO image created in previous compose
if a list of assumptions proves to hold:

 * If image is bootable, buildinstall phase must have been reused too.
 * Compose configuration must have not changed (except for a few
   whitelisted options).
 * Volume ID of the ISO much not have changed.
 * No RPM on the ISO must have changed.

The ISO also contains other files. Changes in extra files and product ID
certificates should be visible in configuration (the SHA will differ).
Similarly any repodata configuration would be reflected in
configuration.

Pungi

Pungi is a distribution compose tool.

Composes are release snapshots that contain release deliverables such as:

  • installation trees
    • RPMs
    • repodata
    • comps
  • (bootable) ISOs
  • kickstart trees
    • anaconda images
    • images for PXE boot

Tool overview

Pungi consists of multiple separate executables backed by a common library.

The main entry-point is the pungi-koji script. It loads the compose configuration and kicks off the process. Composing itself is done in phases. Each phase is responsible for generating some artifacts on disk and updating the compose object that is threaded through all the phases.

Pungi itself does not actually do that much. Most of the actual work is delegated to separate executables. Pungi just makes sure that all the commands are invoked in the appropriate order and with correct arguments. It also moves the artifacts to correct locations.
