Lubomír Sedlář 3b2c6ae72a createiso: Recompute .treeinfo checksums for images 
Running xorriso to modify an ISO image can update content of included
images such as images/eltorito.img, unless we explicitly update the
image, which is undesirable (https://pagure.io/pungi/issue/1647).

However, when the file is changed, the checksum changes and .treeinfo no
longer matches.

This patch implements a workaround: once the DVD is written, it looks
for incorrect checksums, recalculates them and updates the .treeinfo on
the DVD. Since only the checksum is changing and the size of the file
remains the same, this seems to help fix the issue.

An additional step for implanting MD5 is needed again, as that gets
erased by the workaround.

README.md

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.
