Bug description:
  [Impact]

   * For consistency reasons sbin should be ordered before bin in PATH.

  [Test Case]

   * $ env -u PATH /bin/bash -c 'echo $PATH'

  And check that matching pairs in PATH, have /sbin variant leading /bin
  variant.

  [Regression Potential]

   * Ubuntu does not ship duplicate binries, with different behaviour
  between /sbin and /bin, thus all binaries will continue to be found in
  all locations. Also PATH is normally already set in the environment,
  and this change only affects the fallback path when bash is executed
  without any environment, i.e. booting with 'init=/bin/bash'

  [Other Info]
   
   * Original bug report detailing inconsistent paths between various shells.

  $ env -u PATH /bin/sh -c 'echo $PATH'
  /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

  $ env -u PATH /bin/dash -c 'echo $PATH'
  /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

  $ systemd-run --unit test-env env # ... and check journal for PATH
  /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin

  $ env -u PATH /bin/bash -c 'echo $PATH'
  /usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/bin:/sbin:.

  $ env -u PATH /bin/busybox sh -c 'echo $PATH'
  /sbin:/usr/sbin:/bin:/usr/bin

  $ grep 'export PATH=' -r initramfs-tools-0.131ubuntu10/
  initramfs-tools-0.131ubuntu10/mkinitramfs:export PATH='/usr/bin:/sbin:/bin'
  initramfs-tools-0.131ubuntu10/init:export PATH=/sbin:/usr/sbin:/bin:/usr/bin

  dracut.sh has DRACUT_PATH=${DRACUT_PATH:-/sbin /bin /usr/sbin /usr/bin} exported as PATH
  dracut-047+31/modules.d/99shutdown/shutdown.sh:export PATH=/usr/sbin:/usr/bin:/sbin:/bin

  $ cat /etc/environment
  PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games"

  apt & dpkg => should probably initiate /usr/local-less PATH

  Imho the rest should probably be harmonised to:

  /usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin

  From a duplicate

  $ for i in 12.04 12.10 13.04 13.10 14.04 14.10 15.04 15.10 16.04; do echo $i; docker run -it --rm ubuntu:$i bash -c "unset PATH; /bin/bash -c 'echo \$PATH'"; done

  16.04

  I believe later releases of bash, do too include CWD in the built-in
  PATH.
