fixit 4.11 tty device not configured

[john crawford]

hello,

 I'm booting to the fixit cdrom of 4.11 - I think it is disc2
of the iso images.  If I try to do a "fixit" mode remote command
with ssh from the serial console (boot -h) I get
cannot open /dev/tty: Device not configured
If I do the same thing from the vga / keyboard console
it doesn't hang up and it does prompt me for the remote
password.  It works okay there but I can not
copy paste text. What bits of cleverness will allow me to get
my ssh prompt with the primitive fixit environment via serial?

Here's an example.
cdom fixit 4.11 boot -h
[detections]
Mounting root from ufs:/dev/md0c
/stand/sysinstall running as init on serial console

Good Luck!

Fixit# mkdir -p /tmp/dev
Fixit# cp /dist/dev/MA* /tmp/dev/
Fixit# cd /tmp/dev
Fixit# ./MAKEDEV amrd0
Fixit# ./MAKEDEV amrd1

Here, I do various newfs and mounts

Fixit# newfs -b 16384 -f 2048 /tmp/dev/amrd0s1a

mount -o async /tmp/dev/amrd0s1a /mnt

etc

Fixit# export TMPDIR=/mnt/nicetempplace
Fixit# ifconfig em0 alias <machine ip> netmask <mask>
 (alias there not necessary)
Fixit# ls -l / >> /dev/random
Fixit# ls -l / >> /dev/random
Fixit# ls -l / >> /dev/random
Fixit# ls -l / >> /dev/random
Fixit# ls -l / >> /dev/random
Fixit# cd /mnt
Fixit# ssh -e none operator@<ip to dump> 'dump -0f - /' | restore -ruf -

Thanks for any ideas,
