gomote now has ssh support, but it requires images support it.

It looks like the new netbsd-amd64-amd64 builders are not running an SSH server at all.

@bsiegert, could you make the NetBSD images have ssh running (at least on localhost) and have a gopher/gopher user with sudo access to root? Then I can configure the dashboard/builders.go bits to make gomote ssh work.

That would permit others to debug issues like #22871 more easily.

NetBSD 8.0_BETA (GENERIC.201711211410Z)

Welcome to NetBSD!

This system is running a beta release of the NetBSD operating system, aimed
at stabilizing the next formal release.  It is close to formal release quality,
but may still contain bugs, even serious ones.  Please bear this in mind and
use the system with care.

You are encouraged to test this version as thoroughly as possible.  Should you  
encounter any problem, please report it back to the development team using the
send-pr(1) utility (requires a working MTA).  If yours is not properly set up,  
use the web interface at: http://www.NetBSD.org/support/send-pr.html  

Thank you for helping us test and improve this beta NetBSD release.
  
We recommend that you create a non-root account and use su(1) for root access.
