That is the job of the getty task normally. pty is special as the reissue
of the same pty is done as a new device (with new state).

Setting this on the hvc would parallel the PC vt console behaviour but
differ from most other ports.

Anyway its a policy question for PPC64 so if thats how you want it to work
