True. I see this code snippet many times:
BSD has /dev/vc/0 right? I suspect that code is there to support BSD
and make the app portable.
As far as I know the only time Linux has ever had /dev/vc/0 was during
the brief excursion into devfs land. At that time /proc/tty/drivers
was modified to support devfs. But now devfs has been removed and the
device has reverted back to tty0. But /proc/tty/drivers wasn't
adjusted for devfs removal.
fd = open("/dev/vc/0", FLAGS);
if (fd == -1)
fd = open("/dev/tty0", FLAGS);

But since we're killing devfs, changing /dev/vc/0 to /dev/tty0 will be one
of the nails in devfs' coffin :-)
