>Description:
Seems like installing NetBSD 6.0 RC1 sparc64 fails during sysinst.
When running disklabel openpty() fails. 
Perhaps same problem as with netbsd-6/sparc noted in issue #46812 (sysinst 
stops with "openpty() failed" on netbsd-6/sparc)

>How-To-Repeat:
Grab the NetBSD 6.0 RC1 install cd and try to install...
>Fix:
No yet - working on it...
