Hi Matej,
I did review of your recent changes in "ubuntu-xenial-dev" branch. Seems OK.

Good idea to change Nginx logging to syslog as it is supported now. One minor
note is to update following line

"""
#   debug:      /storage/log/nginx-access.log, /storage/log/nginx-error.log
"""

in "system/roles/service-default-web/tasks/main.yml"

Thank you.
