Title:
  initramfs-tools/hooks/udev for network *.link really sucks

Status in systemd package in Ubuntu:
  New

Bug description:
  If one creates e.g. /etc/systemd/network.cu and
  /etc/systemd/network.fc and symlinks  /etc/systemd/network to one of
  them, network setup will fail on reboot, because /usr/share/initramfs-
  tools/hooks/udev does a very poor job: it simply checks for a
  directory instead of the link files and therefore skips copying
  required files to the ram image. Another poor job is done when copying
  the files to the ram image: instead of following symlinks it copies
  them as which in turn makes them useless, because it does not copy the
  related dirs and thus the symlinks point to nothing. So keeping the
  system in an consistent state which such poor scripts is very hard,
  asking for trouble.

  Suggested fix is attached.
