Re: [systemd-devel] : How to modify systemd so that the NTP function is disabled when systemd is first started?
hi Michal & Kevin, I find that just shutting down *timesync* service can't solve the problem. Build time also affects system time. My testing process is as follows: 1. systemctl disable systemd-timesyncd systemctl mask systemd-timesyncd 2. timedatectl set-time "2001-11-30 17:36:46" --- This time is set years ago. 3. reboot system View system time after startup： root@demoboard:~# timedatectl Local time: Thu 2020-04-02 17:27:03 CSTThis time is not the latest time, but it is not the time I set. Universal time: Thu 2020-04-02 09:27:03 UTC RTC time: n/a Time zone: Asia/Shanghai (CST, +0800) System clock synchronized: no NTP service: n/a RTC in local TZ: no root@demoboard:~# check the boot log: Apr 02 17:24:52 demoboard systemd[1]: System time before build time, advancing clock. Apr 02 17:25:02 demoboard systemd[1]: logrotate.timer: Not using persistent file timestamp Sat 2020-04-25 13:45:26 CST as it is in the future. Apr 02 17:25:04 demoboard systemd[1]: Reached target Timers. Apr 02 17:25:38 demoboard systemd[1]: Starting Time & Date Service... Apr 02 17:25:40 demoboard systemd[1308]: systemd-timedated.service: ProtectHostname=yes is configured, but the kernel does not support UTS namespaces, ignoring namespace setup. Apr 02 17:25:42 demoboard systemd[1]: Started Time & Date Service. Apr 02 17:26:13 demoboard systemd[1]: systemd-timedated.service: Succeeded.

Apr 02 17:27:03 demoboard systemd[1]: Started Time & Date Service. It can be seen from the log that after the TimeSync service is disabled, the latest time is obtained from NTP server, but it is not updated to the system. But the system time has also been modified. I'd like to ask you a few questions： 1. When I shut down the TimeSync service, who modified the system time and according to what? 2. What time does the time in systemd relate to? such as build time。 3. How to realize the time of completely independent control system, no matter TimeSync and build time？ thanks， Byron At 2020-04-23 14:25:38, "Michał Zegan" wrote: >As I said, there are symlinks in /etc/systemd/system/*.target.wants that >allows disabling services like this one from starting.

Starting (or not starting) things (under conditions) is a core feature of systemd and well documented. At least I did find the documentation to be good, your experience seems to differ. Maybe you can suggest topics that need to be improved? You create the image, so just do not install stuff you do not want to run there and it won't -- under no circumstances ever. If you want things to start on the other hand, just configure that properly in your image (add unit files and enable them) and it will. PS: If your software has problems with time not increasing monotonically at all times, then your software is broken by design.

Re: [systemd-devel] : How to modify systemd so that the NTP function is disabled when systemd is first started?
As I said, there are symlinks in /etc/systemd/system/*.target.wants that allows disabling services like this one from starting. It is enough to remove the one for systemd-timesync.service from multi-user.target.wants directory. If you can do things via some config files you should also be able to do this W dniu 23.04.2020 o 04:14, www pisze: > > hi Michal and Kevin, > > We applied systemd to embedded Linux, so we often need to update/flash > the whole system.

Re: [systemd-devel] : How to modify systemd so that the NTP function is disabled when systemd is first started?
hi Michal and Kevin, We applied systemd to embedded Linux, so we often need to update/flash the whole system. When we select disable time synchronization function, the embedded system will use the time itself. After we update the system and restart it, we need the time synchronization function is disabled. During the whole startup process, there is no automatic time synchronization, and the previous time is used. Because automatic time synchronization may change its original time. （Because the time of the system itself may be different from that of NTP time.） There is a timesyncd.conf file under the system，can the system automatically turn off the time synchronization function by modifying this file? In this way, when updating, I can save this file to solve this problem. thanks, Byron At 2020-04-17 19:44:48, "Michał Zegan" wrote: >I am not quite sure what you mean, but... generally these are symlinks >in /etc/systemd/system/multi-user.target.wants/ so you could delete them >manually if your intention is to make the actual os image with this >disabled from the start... > >W dniu 17.04.2020 o 12:10, www pisze: >> >> I mean that this configuration can be preserved, even after I update the >> system, this function can be saved. >> >> thanks， >> Byron >> >> >> >> >> At 2020-04-17 18:06:15, "Kevin P.

Both of those changes will stop the service from being started, even when the system is rebooted.

There is no need to modify systemd. $ systemctl disable systemd-timesyncd That command will stop the systemd-timesyncd service from being started.

Dear all， I want to ask a question，How to modify systemd so that the NTP function is disabled when systemd is first started? The default state of systend is to synchronize time from NTP. We can use timedatectl command to disable NTP synchronize time. But if I flash the system, the NTP synchronize time function will auto enable. so I want modify the systemd and disable NTP synchronize time in default state. thanks, Byron___ systemd-devel mailing list systemd-devel@lists.freedesktop.org https://lists.freedesktop.org/mailman/listinfo/systemd-devel
