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.

Did I miss something?

Bug#705056: /etc/default/devpts instructions to set mesg n by default don't work

2013-04-09 Thread Jakub Wilk

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.
