Functions

func ReloadRules

func ReloadRules() error

ReloadRules runs two commands that reload udev rule database.

The commands are: udevadm control --reload-rules

udevadm trigger

Types

type Backend

type Backend struct{}

Backend is responsible for maintaining udev rules.

func (*Backend) Name

func (b *Backend) Name() string

Name returns the name of the backend.

func (*Backend) Remove

func (b *Backend) Remove(snapName string) error

Remove removes udev rules specific to a given snap. If any of the rules are removed then udev database is reloaded.

This method should be called after removing a snap.

If the method fails it should be re-tried (with a sensible strategy) by the caller.

func (*Backend) Setup

func (b *Backend) Setup(snapInfo *snap.Info, devMode bool, repo *interfaces.Repository) error

Setup creates udev rules specific to a given snap. If any of the rules are changed or removed then udev database is reloaded.

Since udev has no concept of a complain mode, devMode is ignored.

If the method fails it should be re-tried (with a sensible strategy) by the caller.
