I since discovered three packages which had somehow regressed to earlier versions when we moved over to Koji (fakeroot, febootstrap and qemu). I've rebuilt all three, but I still can't build my package (libguestfs) which depends on these: http://koji.fedoraproject.org/koji/getfile?taskID=1446422&name=root.log DEBUG util.py:256: No Package Found for febootstrap >= 2.3 [...] DEBUG util.py:256: No Package Found for qemu-system-x86 >= 0.10.5 What can I do about this?

Supports shell scripting, bindings from many languages. http://et.redhat.com/~rjones/libguestfs/ See what it can do: http://et.redhat.com/~rjones/libguestfs/recipes.html
