А если без скрипта, запускается?

script-security 2
up /usr/share/openvpn/update-resolv-conf
down /usr/share/openvpn/update-resolv-conf

Но происходит утечка DNS, а это меня не устраивает.

push "dhcp-option DNS 192.168.0.1"

Но происходит утечка DNS, а это меня не устраивает.

А на сервере, куда подключаетесь, настроен DNS-сервер?
Просто на моём сервере, куда я подключаюсь по OpenVPN, поднят DNS и я добавил в кофиг сервера строчку:

push "dhcp-option DNS 192.168.0.1"

И при подключении берётся DNS сервера, утечек не наблюдал

Из конфига клиента попробуй выкинуть:
user nobody
group nobody

seprik_lo
which: no resolvconf in ((null))

vasek

seprik_lo
which: no resolvconf in ((null))

$(which resolvconf) возвращает нуль, не понимает, лучше прописать полный путь
