Disable systemd-timesyncd.service in image

Disable systemd-timesyncd.service in image

Hi,

I would like to have systemd-timesyncd.service as part of an image but have
it disabled by default.

Right now it is enabled by default which causes some issues.

I've tried systemd_%.bbappend

do_install_append() {
    rm "$D/etc/systemd/system/dbus-org.freedesktop.timesync1.service"
    rm
"$D/etc/systemd/system/sysinit.target.wants/systemd-timesyncd.service"
}

but those symlinks are not part of the package.

I've tried this to remove the link during the package deployment during
do_rootfs
pkg_postinst_${PN}_append() {
    #!/bin/sh -e
    rm "$D/etc/systemd/system/dbus-org.freedesktop.timesync1.service"
    rm
"$D/etc/systemd/system/sysinit.target.wants/systemd-timesyncd.service"
}

But at this stage the links still don't exist.

Which package is actually responsible for enabling the default services /
creating the symlinks? How can we turn some of them off while keeping them
in the image?

Thanks,
-Damien

I think you need to set SYSTEMD_AUTO_ENABLE = “disable” (actually any value
other than “enable”) in your bbappend.

(It looks like SYSTEMD_AUTO_ENABLE_${PN} is intended to work too, but I
can’t verify it at the moment and reading over systemd.bbclass I’m not sure
if it works or not)

The service is deployed with standard systemd package, which doesn't 
have that set as far as I see it (no SYSTEMD_AUTO_ENABLE_${PN} in the 
latest recipe revision)

I think, after browsing through the code of systemd - this "autostart" 
behavior comes from [1].
So I would say you can disable it with a drop-in file at
/etc/systemd/system/systemd-timesyncd.service.d/disable.conf
[Install]
WantedBy=

which also would be charming in a way that it isn't that invasive in the 
build system

haven't tested it though, but you might wanna give that a shot, if 
Aaron's approach doesn't work.

Yes SYSTEMD_AUTO_ENABLE_${PN} doesn't apply to systemd recipe core services
as they are not installed as separate packages.

But I got it working now.

The default enable/disable service are defined in
https://github.com/systemd/systemd/blob/master/presets/90-systemd.preset

So
do_configure_append() {
    sed -i -e "s/enable systemd-timesyncd.service/disable
systemd-timesyncd.service/g" ${S}/presets/90-systemd.preset
}

does the trick

Cheers,
-Damien
