Description of problem:
Shells started by login do not have a controlling tty
(ie, open of /dev/tty fails in the shell).
Problem introduced in  util-linux-2.11f-11.7.1 (not
present in util-linux-2.10s-13.7).

Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1.install pdksh (or ash) rpm
2.set your shell to ksh (or ash)
3.log in on one of the virtual consoles
4. cat /dev/tty
	

Actual Results:  cat failed saying no such device or address

Expected Results:  cat should have been able to open the device.

Additional info:

Guess at the cause: One of the patches in the latest util-linux package
(util-linux-2.11f-logingrp-revert.patch) removes code
which drops the previous controlling tty just before opening
the new tty, with the result that the open does not cause the
new tty to become the controlling tty.
