Package: initscripts,libc6
/etc/default/devpts reads:
# Set to 600 to have `mesg n' be the default
TTYMODE=620
But this doesn't really work. Even if you mount /dev/pts with mode=600,
your pty devices will end up with 620 permissions. This is because
well-behaved software calls grantpt(), which changes the device
permissions.
Either grantpt() should be fixed not to touch permissions if /dev/pts is
a devpts fs (as it did in the past[0]) or initscripts should be fixed
not to claim you can have "mesg n" by default.

I just tried this -- remounted /dev/pts with mode=600 and started
dvtm(1) and stterm(1). This resulted in /dev/pts/{0,1} with $USER:tty,
600. So to be `TTYMODE' seems to work.
This has been fixed in glibc; see bug #806882.
