Title:
  shadowconfig uses "pwck -p" and "grpck -p" which aren't actually
  supported

Status in “shadow” package in Ubuntu:
  New
Status in “shadow” package in Debian:
  Unknown

Bug description:
  /sbin/shadowconfig from the passwd package uses "pwck -p" and "grpck
  -p". On some other Linux systems, the -p flag to these programs says
  to silently fix problems found in those files.

  But the Ubuntu Lucid versions do not actually do that.  The Ubuntu
  Lucid versions ignore the -p option, and then go ahead and prompt for
  confirmation before making changes.

  This can be dangerous at install time. If the install image has
  problems in the group or passwd files (for example, mention of an
  unknown user in the group file), then finish-install's postinst will
  call 06user-setup, which calls user-setup-apply, which calls
  shadowconfig. When that prompts for input, the install will hang.

  This with passwd version 1:4.1.4.2-1ubuntu2.2, which includes
  shadowconfig, grpck, and pwck.
