- STACKIT: Masked `systemd-timesyncd.service` in the OEM sysext. It conflicts with `chronyd.service`, and which of the two ended up running after boot depended on timing. ([scripts#4318](https://github.com/flatcar/scripts/pull/4318))

# chronyd Conflicts= with timesyncd; with both enabled, which one survives the
# boot transaction is a race. Mask timesyncd so chronyd always wins. This can't
# be done from the ebuild: the base image already owns the unit file and
# Portage's collision protection refuses to overwrite it.
