Subject: [PATCH] Remove tmux process runinng check from
configure_bashrc_exec_tmux.
This check can cause troubles since the user must be logged to show up
as tmux running. For example, an evaluation happening through a cron job
wouldn't be able to make this rule work, since no terminal is being
used.
