-`hive-up daemon` - do not have any flags for now.
-
-`hive-up cli --upgrade` - generally not supposed to be called by user. It get called by system service manager (dinit) after hive-up service stop (on reboot or system shutdown)
-When `hive-up cli --upgrade` is called, it checks if `update_on_reboot` flag is set in **DB** or `auto_update` flag checked in **config**, and if `updates_available` in **DB** is non zero. Update routine continue only if this conditios are met.
-
 1. It creates snapshots of `/usr` and `/var` subvolumes
-2. It sets `update_status` to **false** in **DB**
-3. Performs update, and if everything was fine sets `update_status` to **true** in **DB**
-
-After this, system reboots, and on system boot Nyanit figures up what to do with failed updates if any
