# This script tries to install a bwLehrpool satellite server in a (hopefully)
# automatic fashion. It is only verified to work on a Debian 8.x distribution.
# While it may work on any recent Debian-derived distribution using systemd
# this is not guaranteed in any way.
#
# If there were any errors in running this script do the following steps to
# re-install:
# 1. Un-outcomment the call to purge_install near the end of this script.
# 2. re-run the script; ignore any errors like "ERROR 1045 (28000): Access
#    denied for user 'root'@'localhost'". This is caused by mysql root password
#    mismatch; it will vanish on the second run. purge_install will uninstall
#    the packages given in PACKAGELIST_SERVER _and_ purge their configuration.
# 3. re-run the script again; then the mysql root password will be set to the
#    queried password entry. Then the mysql databases and users will be deleted.
# 4. Out-comment the call to purge_install and run the script again for a clean
#    install.
# This cumbersome way will be remedied in the future.
