It turns out that there is another issue (at least one).
I've been wondering about this in a different context, and hopefully
the following makes sense.
In hurd/init/init.c the hardware device is opened.
|| device_open (device_master, D_WRITE, "console", &consdev))
But when multiuser mode is initiated there is no close and reopen in
the init of it's standard io devices, afaict.
Instead term uses:
err = device_open_request (device_master, phys_reply,
D_READ | D_WRITE, tty_arg);
Okay. So why the problem?
I've been noticing that if the initial term process running on console
isn't killed console output doesn't change to the new device.
If process 7 is killed (/hurd/term /dev/console ...) then there is a
lost resource.
Also, processes that cause output to the /dev/console seem to hang
until 7 has been killed and restarted then the options reset.
I'm assuming that both of these are a result of init keeping the
device open, rather than using the translated node as it's roundezous
point (/dev/console).
If this makes sense, it looks like init needs to open /dev/console for
its standard io device _after_ the rest of the system translators have
been started and the terminal device has been started.
I have tried this, and it works, yet this is still an incomplete
solution as /hurd/proc opens the _device_ and /hurd/{auth,exec} are
using proc's (? or more likely as they are children of init init's)
idea of std{in,out,err}.
This isn't so simply fixed as the translator hasn't started yet on
/dev/console so {proc,exec,auth} can't just open /dev/console.
I don't see any clear solution to this problem short of a call back to
frob the stdio for {proc,exec,auth} once init has finished the startup.
The following does seem to work for init, but it is too late in the
game to fixup proc,exec & auth.
