>Description:

Booting an USB install image, like
http://nycdn.netbsd.org/pub/NetBSD-daily/HEAD/201607260800Z/images/NetBSD-7.99.34-amd64-install.img.gz

with boot -a (because I have a broke raid config that I want to recover)
failed. After forcing root to sd0a init dies with "no /dev/console".

However, the filesystem has a perfectly fine /dev/console:

# ll /mnt/dev/console 
crw-------  1 root  wheel  0, 0 Jul 11 19:01 /mnt/dev/console


>How-To-Repeat:
s/a

>Fix:
n/a

 OK, being able to read clearly helps: it is not /dev/console that is missing
 but drmkms failing (cnopen: no console device).

 I added

 userconf=disable nouveau*
 userconf=disable nouveaufb*

 to the /boot.cfg file on the usb stick and then was able to get into
 the installer.

 Can you file a separate PR on the nouveau problem?

 Meanwhile, any idea why it isn't probing the root device correctly?
 That ought to be fixed.

 That is the only problem here, but I think we already have a PR about
 that (this is a pretty new nvidia card, so firmware WILL not be available).

 We need a way to gracefully fail early.

 One of the disks was from an (old) raid set with forced autoroot, so
 the behaviour was just as expected.

 All I see at the moment is 50804 and 51091, neither of which really
 seems to cover it.

  >  We need a way to gracefully fail early.

 Yes. Something like the patch in 50808 might be a starting point, but
 ultimately if the drmkms console fails we ought to fall back to the
 traditional one.

 Maybe file a PR on that? I don't think one exists.

 ah, I guess never mind that part then...
