We are currently migrating most services to systemd as a last step before entering to beta cycle.
In the meantime we plan to finish to integrate the needed bits to limit the need to reboot on update of most packages.
We expect this by the end of the month. If all goes well we would have a RC by the end of the year, and hopefully final release soon after.
If you are willing to help to keep the delays short, please contact John to join Rocket Chat instance or follow the bugs.
The migration to systemd is a sensitive state, every update needs testers to make the everything still works great: the service itself, ability to enable or disable, logs for the service still redirected correctly, or even jeeping the server to boot correctly.
as always and more now, help needed !
