Well...  I'm not sure I understand what you mean by that.
The /dev/pts/* entries do does exist in the host system.  But the bind
mount fails saying they do not exist.  Not sure I understand what the
problem is here but I would like them connected even if systemd doesn't
start getty's on them.  I've used them for other purposes in the past.

Actually, I've decided this is worthy of debugging and there may be
other ways to start a getty (or something else) on that tty.  It really
should work.

Mike
