Title:
  spurious whitespace causes infinite loop in postinst during package
  upgrade

Status in “cryptsetup” package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: cryptsetup

  During and since upgrade from hardy to intrepid cryptsetup's
  postinstall runs into an infinite loop within the update.initramfs.

  (sudo sh -x /var/lib/dpkg/info/cryptsetup.postinst configure >
  cryptsetup-loop 2>&1 attached)

  The reason lies with an extra space in the /etc/crypttab-options that causes the loop (see the second comma):
  not working:  home /dev/sda6 none luks,retry=2, cipher=aes-lrw-benbi
  working: home /dev/sda6 none luks,retry=2,cipher=aes-lrw-benbi
