Title:
  busybox-initramfs needs different compile options to work with
  cryptroot-unlock

Status in busybox package in Ubuntu:
  Confirmed
Status in cryptsetup package in Ubuntu:
  Confirmed

Bug description:
  The cryptroot-unlock script in the cryptsetup package does not work in initramfs.
  It fails because "ps -e" is not available in busybox for initramfs.
  When building the package with

  CONFIG_DESKTOP=y
  CONFIG_EXTRA_COMPAT=y

  the needed commands (ps, grep) with parameter are there and it works.
  Tetsted on Ubuntu GNOME 16.10.
