Bug description:
  Description:    Ubuntu Bionic Beaver (development branch)
  Release:        18.04

    Installed: 1:1.27.2-2ubuntu3
    Candidate: 1:1.27.2-2ubuntu3

  3) Expected my CPIO archive to be fully extracted with proper symlinks
  Command: unxz < /rootfs.cxz | cpio -i

  4) 'Unsafe' symlinks were ignored such as:

  sbin/init -> /lib/systemd/systemd

  With the broken 1.27 sbin/init does not get created at all and my
  debirf initrd fails to load/boot properly.

  libarchive: do not extract unsafe symlinks unless
