Syndicated Device Event Broadcaster

An actor for broadcasting Linux Kernel uevents.

Intended as part of native a device manager for Synit. This is not a replacement for udev/eudev or mdev/mdevd.

Message Schema is at ./uevent.prs.

If you are looking for documentation on how to parse and handle Linux uevents, please let me know when you find it.

Example Syndicate server configuration:

? <machine-dataspace ?machine> [

  <require-service <daemon syndev>>

  <daemon syndev {
    argv: ["/bin/syndev"]
    protocol: application/syndicate
  }>

  ? <service-object <daemon syndev> ?cap> [
    $cap { machine: $machine }
  ]
]

Example message stream:
