I am working with a customer to try to access tty devices from within a
zone. They are using a custom interface card for their tty devices, but
it appears to create pretty standard device nodes and links from
/dev/tty and /dev/cua to the devices.
As a first test, just to verify the ability to add a tty to a zone, I
created a second symlink, /dev/cua/b, that pointed to the same location
as /dev/cua/a. I then added this device to the zone using add device,
set match=/dev/cua/b and restarted the zone. I did not see the new tty
in the zone.
The customer wants to take this a step further, since they use a large
number of these tty ports in their applications. They want to allocate
/dev/cua/ devices to different zones.
Why is this failing? I am able to access /dev/ttya just fine in a zone.
