Package: ntp
Version: 1:4.2.8p10+dfsg-6
I have a very default Buster installation, I've never messed with systemd
settings. Then I installed ntp. I noticed in ntp's systemd config that it
conflicts with systemd-timesyncd which makes perfect sense, these two
should never run together.
However, I noticed that these two guys run in parallel, which is wrong. I
pasted below what I see after a reboot. I will try disabling
systemd-timesyncd but I still wonder, this is broken by default, and why
does systemd even have this service built in?
