>Environment:

FreeBSD 2.2.5-STABLE, last CVSup and make world on February 17th

>Description:

Permissions and ownership of games and dm(8) are screwed up, so that
playing games is no longer possible (dm(8) does not have permission to
access /usr/games/hide)

On another FreeBSD box (last CVSup and make world on February 10th),
the Makefile for dm(8) sets BINOWN to 'games' and BINMODE to 4555.
This is correct because /usr/games/hide is owned by 'games' and mode
700, so dm(8) must be SUID to 'games' to access it.

At some point between February 10th and February 17th, the Makefile
for dm(8) was changed so that it now sets BINGRP to 'games' and
BINMODE to 2555, but /usr/games/hide is unchanged. This means dm(8)
can no longer read /usr/games/hide.

>How-To-Repeat:

As root:

# cd /usr/src/games
# make install

As a user:

$ battlestar
dm: /usr/games/hide/battlestar: Permission denied
