We have two installer.sh scripts.
tarantool.tpl.sh
It is generated every time the script is downloaded from
https://tarantool.io/release/2.6/installer.sh using the
values form the url. It sets up the repo only.
static/tarantool.sh
This script has everything on board for every supported OS.
https://tarantool.io/installer.sh
It installs Tarantool after the repository is set up.
