Lubomír Sedlář 004ef31917 gather: Ignore comps in lookaside repo 
This fixes a case where extra packages are pulled in.

The scenario is:

 * there's a lookaside repo which contains group G which has package P
 * we want to pull group G into the compose, but our definition of G
   does not contain P
 * lookaside repo does not contain package P
 * current package set has P

DNF depsolver will then merge the two definitions and try to get all the
packages. For most cases this is not a problem, since the package is in
the lookaside repo and will not be pulled into the compose. But in the
example above since P is not in lookaside, Pungi will put it into
current compose.

This is also ugly in the depsolving log says it includes package P
because it was in input. But checking comps file does not show it.

The result of this change is that some packages might disappear from
current composes. This can only happen if there is a lookaside which
defines groups with similar IDs, which should be very rare. In cases
where this would be a problem the fix is to explicitly add wanted
packages either to comps or to additional packages.

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.
