Changes in _sd_unit_files http://src.iws.cs.ovgu.de/source/rss/systemd/shell-completion/zsh/_sd_unit_files en Copyright 2005 Java Remove snapshot unit type Snapshots were never useful or used for anything. Many systemd developers that I spoke to at systemd.conf2015, didn't even know they existed, so it is fairly safe to assume that this type can be deleted without harm. The fundamental problem with snapshots is that the state of the system is dynamic, devices come and go, users log in and out, timers fire... and restoring all units to some state from the past would "undo" those changes, which isn't really possible. Tested by creating a snapshot, running the new binary, and checking that the transition did not cause errors, and the snapshot is gone, and snapshots cannot be created anymore. New systemctl says: Unknown operation snapshot. Old systemctl says: Failed to create snapshot: Support for snapshots has been removed. IgnoreOnSnaphost settings are warned about and ignored: Support for option IgnoreOnSnapshot= has been removed and it is ignored http://lists.freedesktop.org/archives/systemd-devel/2015-November/034872.html /systemd/shell-completion/zsh/_sd_unit_files - 36b4a7ba555540edb7648e0f97019280b4ac38de Zbigniew Jędrzejewski-Szmek <zbyszek@in.waw.pl> shell-completion: systemd-analyze verify, systemctl link Some zsh completion helpers were not installed, so completion was broken. Add systemd-analyze verify. Make systemctl link complete only unit names. /systemd/shell-completion/zsh/_sd_unit_files - 2c12a402cb1e8277c271ced8dc9c06d20b8f6017 Zbigniew Jędrzejewski-Szmek <zbyszek@in.waw.pl>
