I think they are unallocated not unlabelled.

They have label tty_device_t and what is needed is chr_file { write
ioctl read open getattr append }.

Possibly it's stuff such as /dev/tty63, /dev/hvc0 and so on.

By the way, recently I had to add these (to use ftp as root from a
console):

kernel_request_load_module(sysadm_t) in policy/modules/roles/sysadm.te
(trying to load ipv6 module)
corenet_tcp_bind_generic_node(sysadm_t) in
policy/modules/roles/sysadm.te (ftp list directory)

And there might be more, I am still testing...

What am I getting wrong here ? Apparently the console is having some
issues (and perhaps not just with ftp) that are not showing up from an X
terminal... So either I am doing something wrong or what's the reason
for having a console much more restricted than X terminals ??

Regards,

Guido
