NTP server choice removed?

[Pepe]

I found the culprit.

https://github.com/openwrt/luci/blob/openwrt-19.07/modules/luci-mod-system/luasrc/model/cbi/admin_system/system.lua#L11

If there is no /usr/sbin/ntpd, then it isn’t shown in LuCI. Once I created symlink, it’s there.

symlink -s /sbin/ntpd /usr/sbin/ntpd

It seems that it should work. I checked to provide NTP server and I see that it should be running:

root@turris:~# netstat -l | grep ntp
udp        0      0 :::ntp                  :::*

This is an issue across all Turris OS versions.
