[ Original question follows ]

Thanks to

Darren Brechman-Toussaint <dbt@b022.aone.net.au>
Jon Zhukovsky <jzhukovs@ntdsm.ML.COM>
and Vo <b5fjrvl@is000895.bell-atl.com>

all of whom pointed out correctly that I should set

        output-device=ttya
        input-device=ttya
        ttya-rts-dtr-off=false
        ttya-ignore-cd=true

As it happens, I had already done that, but was still getting the same
problem. That was pure addle-headed stupidity on my part. For years,
I've been typing "exportfs /export/root/clientname" on SunOS 4.x servers,
and getting the desired result (because exportfs consults /etc/exports
for options like "root=..."). Now, as I struggle to adjust to Solaris 2.x,
I've learned that "share" is the Solaris equivalent of "exportfs", so I
innocently typed "share /export/root/clientname", expecting that it would
consult /etc/dfs/dfstab for the appropriate options. WRONG!!! Shareall
looks at dfstab, but "share" does not.

In a nutshell, my Sparc 10 was hanging because it wanted to write to
its NFS-mounted root filesystem, but it wasn't trusted as root by the
server.

My embarrassed apologies for wasting people's time.

I have a Sparc 10 that has always booted happily with NFS-mounted root and local swap under SunOS 4.1.3, with its console on ttya and without any framebuffer. It used to say this when it booted:

Now I'm trying to boot it under Solaris 2.5, again with no framebuffer and with console on ttya, the only change being the OS. Now it hangs immediately after acknowledging zs1:

Does anyone have any idea what the solution might be?
