Kuti mugwiritse ntchito mu Fedora 33 , yomwe imayika kugawa kuti igwiritse ntchito systemd-yosinthidwa mwachisawawa pothetsa mafunso a DNS. Glibc idzasamutsidwa kupita ku nss-resolve kuchokera ku systemd project m'malo mwa NSS module nss-dns.
Systemd-resolved imagwira ntchito monga kusunga zoikamo mu resolv.conf file zochokera deta DHCP ndi static DNS kasinthidwe kwa ma interfaces maukonde, amathandiza DNSSEC ndi LLMNR (Link Local Multicast Name Resolution). Zina mwazabwino zosinthira ku systemd-zothetsedwa ndikuthandizira DNS pa TLS, kuthekera kothandizira kusungitsa mafunso a DNS amderalo ndikuthandizira kumangirira othandizira osiyanasiyana pamanetiweki osiyanasiyana (kutengera mawonekedwe a netiweki, seva ya DNS imasankhidwa kuti ilumikizane, mwachitsanzo, pazolumikizana za VPN, mafunso a DNS adzatumizidwa kudzera pa VPN). Palibe mapulani ogwiritsira ntchito DNSSEC ku Fedora (systemd-resolved idzamangidwa ndi DNSSEC=palibe mbendera).
Systemd-resolved yakhala ikugwiritsidwa ntchito kale ndi Ubuntu kuyambira kumasulidwa kwa 16.10, koma kuphatikiza kudzachitidwa mosiyana Fedora - Ubuntu akupitiriza kugwiritsa ntchito chikhalidwe cha nss-dns kuchokera ku glibc, i.e. glibc ikupitilizabe kugwira /etc/resolv.conf, pomwe Fedora ikukonzekera kusintha nss-dns ndi systemd's nss-resolve. Kwa iwo omwe safuna kugwiritsa ntchito systemd-resolved, zidzatheka kuzimitsa (muyenera kuletsa ntchito ya systemd-resolved.service ndikuyambitsanso NetworkManager, yomwe idzapanga chikhalidwe /etc/resolv.conf).
