chronyd can work as an NTP server, but unlike ntpd it's disabled by
default. The allow directive can be used in chrony.conf or at runtime
with "chronyc -a allow" to allow NTP client access.

Yes, that's what I meant, support for the samba ntp signd socket. With
chronyd I think the default would be disabled and it would need to be
enabled in chrony.conf when needed.

Maybe chronyd should include files from an /etc/chrony.d directory
where other packages could put their files to enable NTP access, etc?
