Ah, yes, sorry, I did think about that, but forgot to propose the solution in the MR. IMO systemd-timesyncd should be the default time-daemon but also the least preferred option to install, when some other installed package can sync the time. I think the cleanest solution would be virtualbox source building a binary package that Conflicts/Provides/Replaces: time-daemon and sets up time synchronisation with the host ( https://www.virtualbox.org/manual/ch09.html#changetimesync ) If this solution is not viable, then I think the second best option is considering virtualbox-guest-utils as a time-daemon alternative: AFAIK when virtualbox-guest-utils* is installed the guest's clock can be considered to be synchronised to the host and hopefully transitively to a reasonably good source, so I propose changing systemd instead to depend on systemd-timesyncd | time-daemon | virtualbox-guest-utils | virtualbox-guest-utils-hwe. This solution has the disadvantage of not being able to install systemd-timesyncd when virtualbox-guest-utils is present, but should not sync time with the host. IMO this is not a huge problem, since other time-daemon-s can still be installed such as chrony, so the guest can still have accurate time, just not with systemd-timesyncd. Cheers, Balint PS: virtualbox-guest-utils is in contrib, but per #681419 it can still be used as an alternate dependency. -- Balint Reczey Ubuntu & Debian Developer
