neon-phal-plugin-device-updater 0.3.1

Core Module Update Interface

Device Updater Plugin

Exposes a messagebus API to check for and initiate OS-level updates. This plugin expects an update-initramfs system service to be installed to apply InitramFS updates and for the SquashFS update path to be applied upon restarting.

Configuration

The remote URLs and local paths for InitramFS and SquashFS files used by this plugin may be set in configuration. The messagebus API supports branch in data which is used to fill string templates in configured URLs; this is generally used to select a git branch.
