Well, I am really confused here.
- permissions for console (/dev/tty*) are (most probably) set either by
mingetty or by login. Neither pam nor devfsd are responsible for them.
- Mandrake by default is using devpts so you could specify group by
adding gid=5 in /etc/fstab to /dev/pts line. You could also change modes
from default 644 if you want
- still devfs documentation tells us we should not use devpts with
devfs; and I am not sure who wins. pty.c registers /dev/pts/? with
current owner and 600 permissions; and here I have
{pts/1}% ll /dev/pts

that looks like pts/0 got permissions from devpts and others from devfs
because default mount for devpts here is 640
- and /etc/devfsd.conf tells us we must not fiddle with /dev/pt{s,y}
permissions.
So could anybody give ultimate answer on
- should devpts be used in presence of devfs?
- how to manage permissions of pts - i.e. why they cannot be managed by
devfsd?
