Description of problem: 'chrony-helper enable-dnssrv _ntp._udp.DOMAIN' enables instance of a timer 'chrony-dnssrv'. systemd requires for '-' character to be escaped in unit names. (There are few more escaping rules, but for characters which are not used in domain names). Therefore lines like this: #v+ set_dnssrv_timer() { … local timer=$dnssrv_timer_prefix$name.timer #v- have to be written as local timer=$dnssrv_timer_prefix$(systemd-escape $name).timer 'systemd-escape' is a helper program, part of systemd suite. Version-Release number of selected component (if applicable): chrony-2.4-2.fc25.x86_64
This should be now fixed in chrony-2.4-3.fc26. Thanks.
