Like what you like! l'm not here to yuck anyone's yum. You like Systemd cool. You prefer something like Runit cool. You don't care one way or the other, that's fine. Run what you want ... BECAUSE YOU WANTED TO
resolved sucks imo. i usually disable it and manually set the resolv.conf, or use something else. it has no way to force it to check name servers in a specific order and it has a memory so it'll use the same name server for multiple checks even if it's not the right name server. if these things were configurable, I'd agree that it's good. but they're not and it makes it very difficult to use in a lot situations.
