Title:
  hostname: invalid option -- '-b' displayed during boot

Status in initramfs-tools package in Ubuntu:
  Confirmed

Bug description:
  During boot, you can see for a short time "hostname: invalid option --
  'b'" and a line about busybox, and a few other lines.

  Checking /usr/share/initramfs-tools/init, which is copied into the
  initramfs during creation, indeed reveals a hostname call with "-b".

  Also, unpacking my current initramfs and calling bin/hostname, the
  following is displayed, which IIRC coincides very well with the
  message displayed during boot for a short time:

  $ bin/hostname -b
  bin/hostname: invalid option -- 'b'
  BusyBox v1.22.1 (Ubuntu 1:1.22.0-15ubuntu1) multi-call binary.

  Usage: hostname [OPTIONS] [HOSTNAME | -F FILE]

  Get or set hostname or DNS domain name

  	-s	Short
  	-i	Addresses for the hostname
  	-d	DNS domain name
  	-f	Fully qualified domain name
  	-F FILE	Use FILE's content as hostname
  $ 

  The initramfs should only use hostname options which busybox
  understands.
