Nahrazeni/pridani parametru u systemd sluzby

Priklad: chceme zmenit hodnotu Nice pro sluzbu zabbix-agent.service

Vychozi je /lib/systemd/system/zabbix-agent.service, na ten nesahame, protoze by nam ho prepsalo apt pri aktualizaci.

Vyvorime adresar a soubor s nastavenim:

mkdir -p /etc/systemd/system/zabbix-agent.service.d
touch /etc/systemd/system/zabbix-agent.service.d/10-custom-nice.conf

Syntaxe je JMENO.service.d, tedy zabbix-agent.service.d.
