Nothing of this looks specific to linux packaging: Package: dracut-core Depends: 3cpio | cpio, ... cpio does provide a "cpio" program, 3cpio does not. dracut calls "cpio". This is a clear bug in dracut-core. The "error does not always happen" is likely related to the fact that this will work when the cpio package already is/gets installed for a different reason (other dependencies, cpio is "Priority: important"). > Paul cu Adrian
