 Скрипты простой установки могут быть удобны и для нечайников для первоначальной установки,
 после которой можно поправить настройки вручную. Так устанавливать быстрее.
 
+Эти скрипты будут работать и на других системах на базе systemd при условии, что
+уже есть следующие программы :
+
+/usr/lib/lsb/install_initd
+/usr/lib/lsb/remove_initd
+ipset
+curl
+
+Их можно установить вручную при помощи менеджера пакетов вашей ОС.
