NAME
upstart-udev-bridge - Bridge between Upstart and udev SYNOPSIS
upstart-udev-bridge [OPTIONS]... DESCRIPTION
upstart-udev-bridge receives information about kernel uevents that udev(8) has completed and creates init(8) events for them. It emits events which match the pattern "S-device-A" where 'S' is the udev subsystem and 'A' is one of added, changed or removed, which correspond to the past tense of the udev 'action'. See udev(7) and for further details. Assuming /sys is mounted, possible values for subsystem for your system are viewable via /sys/class/. OPTIONS
--daemon Detach and run in the background. --debug Enable debugging output. --help Show brief usage summary. --no-strip Do not modify udev message contents. By default, all udev data will have non-printable bytes removed. This option reverts the behav- iour to not modifying the data in any way. This option is not recommended since specifying it could result in udev(7) events not being emitted as Upstart events should any of your hardware expose non-printable characters to the kernel. You can establish whether this is happening by running without specifying this option but with the --debug option. --verbose Enable verbose output. EXAMPLES
Some examples of Upstart events generated by this bridge: net-device-added Event emitted when a network device is added. net-device-removed Event emitted when a network device is removed. graphics-card-added Event emitted when a graphics device is available to the system. NOTES
This is a temporary tool until init(8) itself gains the functionality to read them directly; you should not rely on its behaviour. AUTHOR

NAME
systemd-udevd.service, systemd-udevd-control.socket, systemd-udevd-kernel.socket, systemd-udevd - Device event managing daemon SYNOPSIS
systemd-udevd.service systemd-udevd-control.socket systemd-udevd-kernel.socket /lib/systemd/systemd-udevd [--daemon] [--debug] [--children-max=] [--exec-delay=] [--event-timeout=] [--resolve-names=early|late|never] [--version] [--help] DESCRIPTION
systemd-udevd listens to kernel uevents. For every event, systemd-udevd executes matching instructions specified in udev rules. See udev(7). The behavior of the daemon can be configured using udev.conf(5), its command line options, environment variables, and on the kernel command line, or changed dynamically with udevadm control. OPTIONS
-d, --daemon Detach and run in the background. -D, --debug Print debug messages to standard error. -c=, --children-max= Limit the number of events executed in parallel. -e=, --exec-delay= Delay the execution of RUN instructions by the given number of seconds. This option might be useful when debugging system crashes during coldplug caused by loading non-working kernel modules. -t=, --event-timeout= Set the number of seconds to wait for events to finish. After this time, the event will be terminated. The default is 180 seconds. -N=, --resolve-names= Specify when systemd-udevd should resolve names of users and groups. When set to early (the default), names will be resolved when the rules are parsed. When set to late, names will be resolved for every event. When set to never, names will never be resolved and all devices will be owned by root. -h, --help Print a short help text and exit. --version Print a short version string and exit. KERNEL COMMAND LINE
Parameters starting with "rd." will be read when systemd-udevd is used in an initrd. udev.log_priority=, rd.udev.log_priority= Set the log level. udev.children_max=, rd.udev.children_max= Limit the number of events executed in parallel. udev.exec_delay=, rd.udev.exec_delay= Delay the execution of RUN instructions by the given number of seconds. This option might be useful when debugging system crashes during coldplug caused by loading non-working kernel modules. udev.event_timeout=, rd.udev.event_timeout= Wait for events to finish up to the given number of seconds. This option might be useful if events are terminated due to kernel drivers taking too long to initialize. net.ifnames= Network interfaces are renamed to give them predictable names when possible. It is enabled by default; specifying 0 disables it. SEE ALSO
