version 1.2.dev
freebsd init script: cleanup
debian init script: replace tab to spaces
init scripts: user configurable
debian init script: bugfix - remove unrelated message
  * on start, message 'from: can't read /var/mail/computers' was printed
  * in the service description part was a uncommented line which started with
    'from' - there is also a command 'from', which was then executed
init scripts: logfile as var
debian init script: use 'lsleases -x' to shutdown server
  * start-stop-daemon with PIDFILE not usable, because the server
    instance is in an bash instance wrapped (for output redirection)
  * output redirection per start-stop-daemon (with flag --no-close)
    not in supported ubuntu 12.04 possible
rpm init script: cleanup stop function
debian init script: add systemd service descriptor
