If anyone's interested, I have patched /etc/dump to use stdin rather than
/dev/tty. This was necessary to allow backup operators to log into one
system	and run a shell script that uses rsh to perform dumps of all our
fileservers, rather than having to log into 8 or 9 different machines each
time. Not sure if I have a script of the adb session, but the binary has a
second patch that causes dump to use the service "shmtf/tcp" rather than
"shell/tcp" when using a tape drive on a remote host. This patch was made
so that we could use a custom rshd for remote backups. That second patch
is no problem to get around, though.
