Overview

Represents a driver update.

This class will handle driver updates which are applied yet. The main purpose is to re-apply them after the installer's self-update has been performed.

At this point, two kinds of driver updates are considered:

  • Driver Update Disks (DUD): a directory containing different subdirectories, one of them called inst-sys.
  • Packages: are stored in a squashed filesystem which is mounted in /mounts directory.
