Right, I just checked the linux kernel source. It's even a bit worse,
only root can do TIOCCONS on linux:
static int tioccons(struct file *file)
{
if (!capable(CAP_SYS_ADMIN))
return -EPERM;
The way it is done in other UNIXes makes much more sense, see e.g.
the SRIOCSREDIR ioctl in solaris.
Cheers,
Michael.
