Title:
  ifupdown should not hard-depend upon 'mountkernfs' and 'urandom'

Status in ifupdown package in Ubuntu:
  Confirmed

Bug description:
  '/etc/init.d/networking' for 'ifupdown' starts with:

    # Required-Start:    mountkernfs $local_fs urandom

  it would appear that 'mountkernfs' and 'urandom' are not hard-
  dependencies, and their presence prevents successful installation in
  virtual machines in some circumstances.  This was reported by Neal
  Gompa/<Pharaoh_Atem> on #ubuntu-devel whilst working on support for
  Suse Open Build System (OBS) to build Xenial packages:

  http://changelogs.ubuntu.com/changelogs/pool/main/i/ifupdown/ifupdown_0.8.10ubuntu1/changelog

  Full and snipped output logs are at:

    https://paste.fedoraproject.org/358315/66065146/

  in particular:

    [  530s] [239/256] installing ifupdown-0.8.10ubuntu1
    [  530s] Creating /etc/network/interfaces.
    [  531s] insserv: Service mountkernfs has to be enabled to start service networking
    [  531s] insserv: Service urandom has to be enabled to start service networking
    [  531s] insserv: exiting now!
    [  531s] update-rc.d: error: insserv rejected the script header
    [  531s] dpkg: error processing package ifupdown (--install):
    [  531s]  subprocess installed post-installation script returned error exit status 1

  The reporter tested that commenting out 'mountkernfs' and 'urandom'
  allowed the ifupdown '/etc/init.d/networking' init-script to
  successfully complete.

  Ideally a hard-dependency should not be declared if it is not actually
  a hard-dependency, and introduces a regression by  preventing
  successfully installation in circumstances that are reported to have
  worked previously for installing earlier Debian/Ubuntu versions on
  OBS.
