Jan Kaluza fcf1442f71 Support generating ISOs when using link_type="symlink". 
When `link_type = "symlink"` is used, the packages are in fact symlinks
to /mnt/koji. When graft points file is generated, the paths in this graft
points file point to symlinks and therefore symlinks are copied into the
generated ISO file instead of real files.

In this commit, the code to generate the graft points file is changed
so it resolves the symlink to real file stored on /mnt/koji. To make
this code safer, it does such resolving only in case the symlink points
outside of `compose.paths.compose.topdir()`. Therefore you can still
generate ISO file with symlink pointing to file stored within the ISO
file itself, although this is not done currently afaik.

The main reason for this is to be able to generate ISO files even
without hardlinks (which would need read-write access on /mnt/koji)
and without copying all the packages from /mnt/koji to local storage.

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.
