Description:
Somewhere after upgrade to consolekit 0.4.3, when I start X session, tty used by X remains owned by root.

I login to tty1, it becomes owned by me, group tty, perms 0600. Then I run startx
my main exec line in .xinitrc:
exec ck-launch-session dbus-launch --exit-with-session openbox-session

X starts on tty7, but /dev/tty7 remains owned by root, group tty, perms 0620. It breaks scripts relying on fgconsole


$ ck-list-sessions
Session2:
unix-user = '1000'
realname = ''
seat = 'Seat1'
session-type = ''
active = TRUE
x11-display = ':0'
x11-display-device = '/dev/tty7'
display-device = '/dev/tty1'
remote-host-name = ''
is-local = TRUE
on-since = '2011-04-16T13:41:35.057401Z'
login-session-id = '1'

$ stat /dev/tty7

Xorg is the process owning the tty, and as it's setuid root, it runs as root. This is not a consolekit bug, afaik consolekit doesn't even set permissions anywhere.
