tty muxer
=========

apt-dater uses a 3rd party tty muxer. In version before apt-dater 1.0.2
only screen(1) was supported. Since apt-dater 1.0.2 tmux(1) is also
supported. The tty muxer backend is selected at compile time.


screen
------

For each session an induvidual screen process is launched. Sessions are
not accessible by other users (limited by screen).


tmux
----

For each host a shared tmux daemon is created by the first session. Sessions
can be shared between users. The default configuration (~/.config/*.xml)
will include global configuration from /etc/apt-dater/. You have to setup
the configured global directories to be accessible by all participating
users:

# addgroup apt-dater

# mkdir /var/cache/apt-dater
# chown :apt-dater /var/cache/apt-dater
# chmod 02770 /var/cache/apt-dater

# mkdir /var/lib/apt-dater
# chown :apt-dater /var/lib/apt-dater
# chmod 02770 /var/lib/apt-dater

Due to the relaxed umask config in /etc/apt-dater/apt-dater.xml and the set
group ID on execution of the directories all files and tmux sockets are
accessible by all users belonging to the group apt-dater.
