Logout root after tmux detach

If it is sufficient that your ecryptfs protected home directory is not unmounted when you log out, you can remove ~/.ecryptfs/auto-umount and it will stop unmounting when you logout (which is what I do, debian wheezy). I found this thread on askubuntu about the same thing, however the script presented doesn't work. Here is a modified version that does.

#!/bin/bash

if tmux ls 2>&1 >/dev/null; then
  # tmux is still running, do not auto-unmount
  rm $HOME/.ecryptfs/auto-umount
else
  # no tmux server, auto-unmount is OK.
  touch $HOME/.ecryptfs/auto-umount
fi

As mentioned in that thread, you can have it execute as part of your logout script.

Unfortunately, there isn't a good way to allow it to unmount and have all of your applications automatically cd on tmux attach. If that is required, you might consider a tmux key macro to issue a command to each window and panel if you keep your applications in regular locations or have a sane way to accurately detect what app is running in that window or panel; I personally never figured that out.

I'm not sure since what versione but now you can use

tmux new -A -s <session-name>

The -A flag makes new-session behave like attach-session if session-name already exists
