Depends on the overall system security policy. If it really is
a single user desktop (no rlogins, one console, and otherwise
set up as "safe" as possible) there's no threat. I consider
anything else as likely insecure already ... though I agree that
a machine set up with a bunch of dedicated webcams will want to
have those webcams owned by their application, not any user.
Is there someplace with a writeup of the flexibility available
with all of the currently-stable devfs-ish tools? With all the
happenings with devfs and usbdevfs (etc) I've yet to see even a
forwarded email.
For example, I didn't know that there was support in "the console
login modules" for that sort of mechanism. The last time that I
looked at it, it only know about the particular /dev/tty the login
was being performed on.
