[Bug 1242913] Re: /dev/pts being created with mode=600 by Lxc

[John Peacock]

Rebuilding IO::Tty on a system which lacks grantpt() and pt_chown()
fixed the problem with the script not being able to create a pty.

So the only remaining piece is to understand why /dev/pts is being
chowned to root:root.  Looking at src/lxc/conf.c, I can see where that
directory is being created.  This isn't specific to Centos; it happens
equally with Ubuntu instances.

The attached patch (soon to be submitted upstream) appears to be a belts
and braces approach to ensure that the /dev/pts directory has the
correct group ownership.  Using both patches completely fixes this bug
for me.
