Replacement of Windows NTP server with Linux

I have been running a Windows PC with Lady Heather and Meinberg NTP monitor
for 6-7 years now. One very annoying problem with Windows 10 has been the
forced updates and reboots knocking my headless configuration on it's arse.

So I have been experimenting with various Linux options, first with RPi 4
with a compiled version of LH, and now with Ubuntu Server 20.04 using
chrony, gpsd and of course the attached GPS device (NMEA for now, but being
replaced with the Tbolt attached to the Win 10 PC).

All seems to be working fine, the chronyc monitoring looks good and a run
of w32tm /stripchart /computer:<ip> looks good compared to the Win 10 peer.

I'll next be wiring-up PPS for the first time for the next round of tests.

For you X experts out there, is there anything I need to watch out for? TIA

Ubuntu server is great - I’ve been supporting applications on Ubuntu for
over 10 years now and it is easy to maintain and update.

Set Ubuntu up absolutely minimally - no packages installed unless
absolutely necessary. Certainly no X11 or GUI desktop. This way the number
of security updates will be lowest.

Instead of chrony , I use ntpd because of 30+ years experience under my
belt with that. (As well as experience customizing I/O for esoteric
refclocks like WWV audio).

Russ,
You could have also just run gpedit.msc (group policy editor) to turn off the updates/reboots in windows 10.
It comes standard on pro but can be added to home also I believe.
