DEBIAN8 Modifying the startup default run level

Things need to know:

1) Systemd boots towards the target given by "Default.target". This was typically a symbolic link to the actual target file.

2) Systemd keeps it ' s targets in/lib/systemd/system And/etc/systemd/system. A file In/etc/systemd/system takes precedence over those shipped with the OS In/lib/systemd/system-the intent are that /ETC/SYSTEMD is used by systems administrators and/lib/systemd are used by distributions.

Debian as-shipped boots towards the graphical target. Can see this yourself:

$ ls -l /etc/systemd/system/default.target... No such file or directory$ ls -l /lib/systemd/system/default.target... /lib/systemd/system/default.target -> graphical.target

So-to-boot towards the multiuser target all your need do are to-put in own target:

$ cd /etc/systemd/system/$ sudo ln -s /lib/systemd/system/multi-user.target default.target
