Usage of slapos branch should be only in special cases, no reason to not test against master branch

Compatible with debian/ubuntu/opensuse, it is used to tweak few variables
needed for run KVM or optimize network transference or load some important
modules.

This script is not enabled by default, because it should be used with care.

This script is only supported for OpenSuse and "apt-get types" of Linux.

 This preserve old tapVPN working while upgrade the packages.

This changes makes easy to development packages by enabling/disabling some parts.

Systems which requires faster responses of timeout should adjust default configuration for smaller numbers

This helps us to test packages on under a development channel

This package is required to build python with ssl support, probably this should be solved on recipt itself in future

It was removed by mistake

This commit should be eventually rebased and this msg edited

 - use sh -e instead set -e
 - use title instead email when configure re6stnet

  This script still on experimental stage, only works for debian 7.
  The preseed.cfg is a pure netinstall debian automation setup, it
  don't install slapos by itself for now.

In case of vpn, use it.

No need to run slapgrid, as it is run by cron every minute.
Also follows rule of least surprise.
