Quoting myself,
I am netbooting a sparcstation5 with NetBSD 6.1 for installation. At
the disk initialization stage, I get,
Status: openpty() failed
Command: disklabel -w -r -f /tmp/disktab sd0 'CFP1080E SUN1.0'
Hit enter to continue
So I installed the system from the command line and I had some similar issue once it was up and running, while trying to connect to it through SSH,
Server refused to allocate pty
tset: standard error: Inappropriate ioctl for device
so I had to add this to fstab,
ptyfs /dev/pts ptyfs rw 0 0
and mount /dev/pts
It should be the same problem with sysinst since the day where LOTSA was
dropped in favor of ptyfs. Maybe someone fix that or should I send a
PR? I won't have access to that sparcstation in the next days, though.
