Where does the name originate?

Why rename it? LocLCS218301788 existed previously in /etc/udev/rules.d/70-persistent-net.rules but I shortened the name to LocLCS1788; as evident here. root@joule:/etc# grep 1788 /etc/udev/rules.d/70-persistent-net.rules ATTR{dev_id}=="0x0", ATTR{type}=="1", KERNEL=="eth*", NAME="LocLCS1788" The old name "LocLCS218301788" was dredged up from somewhere outside /etc/. Where? Old NIC names are cached? Thanks, ...
