Package: systemd Version: 247.3-3 Tags: bookworm sidsystemd used to include systemd-timesyncd. Now it is split out to a separate binary package. Thanks. However, systemd now depends on systemd-timesyncd, so we cannot really remove it (unless installing something like ntp). For containers, having a time-daemon is not useful and we want to reduce the filesystem as much as possible. Therefore it would be good to reduce the dependency to Recommends.
A few thoughts. The disk footprint of systemd-timesyncd is rather small. It would be good to know which kind of containers your have in mind.docker-style (minimal) without an init or with a full-blown init like lxc (fat)? The former doesn't have init/systemd installed (and thus no systemd-timesyncd), the latter does and systemd itself is much bigger disk footprint wise.
If we bump the prio of systemd-timesyncd, those minimal containers will now suddenly get systemd-timesyncd by default (which in turn pulls systemd). So this would be a regression. You'd have to be careful to omit systemd-timesyncd when building the container image.
For fat containers, having systemd-timesyncd installed doesn't really gain you a lot (and is no regression compared to buster, where it was folded in). Runtime-wise, having systemd-timesyncd installed, is not a problem either, as systemd-timesyncd.service has ConditionVirtualization=!container
