Hello folks. I just noticed something that I’m sure has been true forever, but I checked and it’s still true on my 12.3-STABLE system.
In the daily run output, I’m seeing the network interface names truncated. This comes from netstat -I apparently only rendering the first 5 characters of the interface name. Many of my systems have `vlanNN` interfaces, but they show up as `vlanN` in netstat output. Unfortautnely, I have all of vlan1, vlan3, vlan11, and vlan33 on one of my systems (plus others). This makes it impossible to identify which of the lines of output are which interface:
vlan0 1500 <Link#7> 90:e2:ba: dd:ee:ff 7898136066 0 0 6455161338 0 0 0

Can someone check if this is still so in 13 or CURRENT, and/or let me know if I’m doing something wrong?
