Systemd Kills Off Shutdownd
The original shutdownd implementation for handling shutdown-related tasks within systemd has been killed as the functionality has now moved into logind. With a round of logind improvements sent in today by Daniel Mack, logind handles the responsibilities once managed by shutdownd, as such the old implementation has been killed.
Logind now has .ScheduleShutdown and .CancelScheduledShutdown methods and /run/nologin and /run/systemd/shutdown/scheduled, among other additions for providing shutdown parity to the now-former shutdownd.
These changes will be part of the upcoming systemd 220 release, which is becoming quite a huge release. In the two months since systemd 219 there's been the new EFI boot manager, greater Btrfs support, a reboot to EFI option, and much more.
