I'm running hotplugd on 5.2-current snapshot build from Aug 1. As I was
configuring it, I found that I could not terminate a running hotplugd and
then start it, nor could I restart it from
"/etc/rc.d/hotplugd restart".
Looking at the source, it seems that hotplugd is expecting SIGQUIT in
order to shutdown cleanly and move into reaching close(devfd), but it
appears to still have a hold on /dev/hotplug even when it gets SIGQUIT,
and then cannot reopen the busy device to start again.
Any thoughts on how to get hotplugd to restart cleanly?
Thanks!

Reboot and get hotplugd working again:
$ pgrep hotplugd

$ grep "terminated" /var/log/daemon ### Logfile rotated
$ sudo /etc/rc.d/hotplugd restart
hotplugd(ok)
