Add pseudo device in zones

Question

How can one add a pseudo device to a zone? We have a
pseudo device which serves as an application entry to a kernel module. It does ioctl's to the kernel module.
When I create the device in the global zone and then do an
add device
set match=/dev/rxp
end
in the zone configuration and then
configure the zone with zonecfg, it does not complain.
But when I check the /dev directory in the zone for the /dev/rxp, I do not see it. The documentation specifies that the zone configuration
will create some pseudo devices, /dev/null, /dev/zero and others.
If the answer is that the configuration does not let you add
pseudo devices today, then when will it?
thank you.

Although I'm not positive in this I do think it may be a while before something like this will be implemented. After all; the primary task of a non-global zone is security by shielding it off from the main zone and thus seperating several resources.
However; do note that your /dev directory in the global zone is not fully shared with the one of the non-global zone. It has its own seperate dev directory which can be found in the same directory as the zone's rootpath. You may give it a try in there, but personally I have some serious doubts to the success of this approach.
