Log:
  Notify devd(8) when a process crashed.

  This change implements a notification (via devctl) to userland when
  the kernel produces coredumps after a process has crashed.
  devd can then run a specific command to produce a human readable crash
  report.  The command is most usually a helper that runs gdb/lldb
  commands on the file/coredump pair.  It's possible to use this
  functionality for implementing automatic generation of crash reports.

  devd(8) will be notified of the full path of the binary that crashed and
  the full path of the coredump file.

What advantage does putting this in devd have over a standalone daemon for crash reporting?  Is it just the ease of implementation to leverage the existing infrastructure?
 
Well, I want to automatically inspect all the programs that crashed in a given system.  I don't see how you can do that with a standalone daemon.  Or maybe I didn't understand what you meant.
