I have learned to assign label could get fixed node for disk.
I am curious is there similar way to get fixed node for other devices?
I have one UPS which offer power supply to FreeBSD 11. The UPS monitor service is running in FreeBSD well.
The node is being monitored: /dev/ugen0.5.
A potential problem is that once somebody plug in USB hub or similar device and restart, the UPS USB port will be changed to another ugen number. For example /dev/ugen0.7.
In that case the UPS monitoring will be failed.
is there a way (like disk label) to assign fixed "label" to USB device, then I could use that fixed label for monitoring service.
