Title:
  binfmt-support doesn't honor flags: in /usr/share/binfmts/foo

Status in “binfmt-support” package in Ubuntu:
  Won't Fix
Status in “qemu-linaro” package in Ubuntu:
  Fix Released

Bug description:
  Binary package hint: binfmt-support

  qemu-user-static ships a number of binfmt handlers under
  /usr/share/binfmts which are registered in the postinst using 'update-
  binfmts --import qemu-$target'.  In natty, the resulting registrations
  under /var/lib/binfmts (and in /proc/sys/fs/binfmt_misc) don't respect
  the value of the flags: field set in the source file.  As a result,
  foreign-arch suid binaries can't be run under qemu because the kernel
  has been told to use the suid bit from the non-setuid qemu
  interpreter, instead of the one from the target binary.

  Please fix update-binfmts to respect the flags: field, which I think
  worked in previous versions.
