# A problem I've been trying to solve for a long time.  To start a
# remote emacs client in the background, the ssh session needs to stay
# alive to forward the connection and emacsclient on the remote host
# needs stdin to be a terminal.  I've only ever found two ways to work
# around this: use dtach or screen, or do the login manually and wait
# until the X window is open.  It seems that then there is no longer
# any attempt to access the controlling tty.

# I'm using dtach instead of screen as it's uses a single socket per
# terminal and doesn't require config files.

# Can't share a non-X master session, so be own master.

dtach -c $SOCKET ssh -XM $HOST -t "$@"

# dtach -n $SOCKET ssh -XM $HOST -t "$@"
# I don't understand this shit...
