udev rule don't work

[octopic]

Hi, in the wiki documentation you give a tips usign udev and getID, but for some people it don't work. I found the problem : udev run a root and don't have the opt/ros/distro/lib in the shared library.
To add it you must run ldconfig as root so :
$ su

ldconfig /opt/ros/melodic/lib

I was in the /opt/ros/melodic/lib directory when I did the command but it seem not to be necessary
It works for me.
